Product Review (August 2008) - Belkin PureAV™
Hybrid AVU1500 UPS with PureFilter Technology

By Kevin Nakano

Belkin has taken the power conditioning market seriously with a number of components under the PureAV™ name. Recently, they have taken it a step further with the introduction of the new PureAV Hybrid AVU1500 UPS with PureFilter Technology. The design protects equipment and provides an advanced UPS to keep components running in the event of a power outage. The unit is designed to safeguard the content of your personal video recorder, satellite receiver, or any other home theater component that may need backup power. Belkin has combined their PureAV PureFilter Technology with the power of a 1500VA, 1000-watt, battery-backup system (UPS). The AVU1500 cleans, protects, distributes, and provides backup power to your entire system. Several features included in the design sets it apart from other products, so we will take a detailed look at the product.

Battery Tray
A large portion of the weight in the AVU1500 is contributed by the heavy lead-acid batteries used for backup power. As with all lead-acid batteries, there will come a time when they need to be replaced. Belkin makes it easy to remove the 30 pound battery tray by providing a flip out panel on the front left side of the chassis where four screws hold the tray in place. The tray slides out making it easy for the user to replace the batteries when needed.

The main display provides status of the unit's operation. The incoming line voltage is displayed on the left in with large segments. The current being drawn by the connected components is displayed on the right. Should the incoming line voltage go too high or too low the AVR (Automatic Voltage Regulation) circuit activates to compensate for the line voltage and displays the AVR ON symbol on the screen. Ground and Wiring status are provided with good/bad indicators. Switched, Remote, Audible Alert, and Override On/Off status are also displayed. The remote indicator lets the user know if the AVU1500 is being controlled by another component such as a preamplifier. The Switched button controls the switched outlets on the unit with status on the screen. The Dimmer button cycles through different backlighting levels and includes an off setting. Pressing and holding the Test button for three seconds starts a quick shutdown test to check the setup. Holding the Test button for ten seconds starts a deep battery test which is designed to discharge and recharge the battery to help refresh its chemical contents. The Audible Alert button mutes the alarm during an alert and changes the corresponding status indicator. The Stage Time button cycles through the three power stages indicating the amount of time left on each of them. These power stages are designed to shed loads to preserve power to the most critical components. The Override Stages button overrides the sequential shutdown of the three power stages and changes the indcator.

There are several other indicators on the screen that give the user status. The Battery ON indicator activates when the unit is running from batteries during a power outage. The Overload indicator goes active when the unit is being overloaded. The Battery Load Meter has five segments that show the load on the UPS. When the load approaches 1000W, all five segments will begin to flash indicating the unit has reached it's maximum output. The Battery Charge Meter shows the level of the batteries with a five segment display. Should the batteries in the unit go bad, the Replace Battery indicator will turn on.

Rear Panel
The AVU1500 has a detachable power cord and a built-in fan for cooling. The fan is especially important when the UPS is active with a heavy load as significant heat is generated. The rear of the AVU1500 is designed with four banks and three stages of powered outlets. Stage 1 includes Bank D (High Power) with two outlets optimized for subwoofers and power amplifiers. Stage 2 includes four Bank C (digital filtering) outlets and two Bank B (Analog filtering) outlets. Stage 3 has four Bank A outlets with digital filtering. Each Bank can be configured using the Filter Bank Settings controls. The Banks can be Always On or Switched with a delay (5, 10, or 15 seconds) or without a delay. Protection is provided for cable, satellite, and antenna connections as well as for phone (RJ-11) and wired ethernet (RJ-45) interfaces. A USB and RS232 connection is provided with extensive home automation command and control through the RS232 interface.

The Remote IN section is used to turn (trigger) the unit ON using the DC input or switched AC from the source such as a preamplifier. The On/Off switch in the Remote IN section enables/disable the remote function. Once the unit is triggered, the unit can send a DC trigger with or without a delay. The same delay setting used for the Filter Banks will be utilized.

The AVU1500 also includes an IR Blaster that sends out an IR command to any one of the components during the shutdown phase. The Blast Stage switch setting (1, 2, or 3) determines when the IR command is sent out. The AVU1500 has the ability to learn an IR command from an existing remote and includes an IR detector with a Teach button. An LED indicator provides the learning process status to the user.

Color Change
When the utility power fails, the display on the AVU1500 turns orange indicating a problem with the incoming power. The three stage power indicators show what outputs are active and how much time is left on the batteries. The
AVU1500’s batteries will automatically
supply backup power to all the equipment connected to its rear-panel power outlets. While the power reserve is large in the unit, there is a limited amount of energy stored in the batteries. The unique design of the AVU1500 allows equipment to be shut down in stages. This keeps the most important components powered for the longest time. There are three stages with Stage 1 (Bank D) shutting down after the battery runs down to 90% of maximum capacity. Bank D is designed to power high current components such as amplifiers and subwoofers. Stage 2 (Banks B & C) shuts down when the power reaches 50%. Bank B & C are for non-critical devices such as CD and DVD players. The remaining power keeps Stage 3 (Bank A) powered for as long as the batteries can keep the inverter running with the attached load. Bank A is designed for satellite/cable boxes, DVRs, and VCRs. As each stage shuts off, less energy will be drawn from the batteries thereby prolonging the remaining supply of battery power to the most critical (Bank A) devices.

We connected a Mitsubishi LT-52133 52" LCD display along with a variety of A/V components for testing. The display alone draws several amps under normal conditions whereas the digital components have much lower power consumption. Our test simulated a power outage by pulling the plug from the wall. None of the connected equipment was even phased by the loss of incoming power. Even the high current being drawn by the display did not show any signs of power transfer to the AVU1500 UPS. The display turned orange indicating that power failed and the instrumentation on the LCD screen provided feedback on the system vitals. As time continued, the unit began to shed power at the 90% and 50% battery capacity levels starting with Stage 1 and then Stage 2. This keep Stage 3 components running for an extended amount of time until no more energy was left in the batteries. The
controls for the unit are simple and easy to understand and offer the flexibility needed to customize the A/V system.

Belkin's new PureAV™ Hybrid AVU1500 UPS offers complete power protection with the added benefit of backup power in the event of a blackout. The build quality of this unit is exceptional and the features are some of the best available on any power conditioner. Whether you plan to rack mount the unit or place it in a cabinet, the AVU1500 looks great. In addition, rack mount hardware is included with the unit.

Usually when connecting A/V components to a power conditioner you get the benefits of surge protection and if you are lucky, some form of voltage regulation for when utility power or house loads vary. Belkin has combined this capability with complete battery backup in the UPS to keep key components in your system fully active in all types of events. Whether it is sagging line voltage, power transients, brownouts or complete power failure, the Belkin PureAV AVU1500 UPS covers it all. With a street price of around $850, the PureAV™ Hybrid AVU1500 UPS is a great deal offering some of the most advanced and comprehensive power management features we have used to date. Belkin also includes their $500,000 Connected Equipment Warranty along with a 3-year product warranty. If you are serious about protecting your equipment, the PureAV™ Hybrid AVU1500 UPS is a worthy addition to your system.
