Review (June 2005) - Panamax
By Kevin Nakano
Panamax, recently acquired by Linear LLC, has responded to a demand for emergency backup power for today's A/V products, venturing outside its traditional power protection market. The new MAX® 1500-UPS offers customers a powerful 1500VA / 1000 watts of uninterruptible power with a true sinewave output and improves upon conventional UPS designs by adding the ability to send IR commands to connected equipment in the event of a power failure. Furthermore, the unit has the capability to learn IR commands directly from any existing remote control with its built-in IR detector and sampling system. The unit has a slick contemporary look instead of the industrial face seen on most UPS designs and offers noise filtration and the patented over/under voltage protection circuitry. A 10-foot heavy-duty detachable power cord, a pair of rack mount ears, a phone cord, DB9 serial cable and the Home Cinema Power Control software are included.
The unit also provides protection for Ethernet or telephone connections using a pair of RJ-45 connectors. Pins 4 & 5 have a 260-volt clamping level while pins 1, 2, 3 & 6 are clamped at 7 volts. This allows the RJ-45 connectors to be used for either computer or phone applications.
The Setup button opens a new window that allows the user to select the communications port as well as various delay times. The time to initiate a shutdown sequence when a power failure occurs is set for 5 minutes (300 seconds), but can be adjusted through the software interface. The time between the power failure to the initial warning can also be defined in this panel. Pressing the red Run button initiates a self-test for a duration defined by the UPS Self-Test time. The software also provides the user with an audible voice and an alarm, both of which can be disabled through the user interface.
The Advanced settings allow the user to set the low battery cut-off voltage. The Low Voltage Failure (88V-97V) and High Voltage Failure (137V-147V) values determine when the UPS switches to battery backup. The Battery-Mode Output Voltage setting defines the output voltage of the UPS when running from the inverter. The user can select from 110V, 120V or 130V. If a HTPC (Home Theater PC) is used with this unit, the user can determine the when the shutoff occurs based on Low Battery HTPC Shutoff setting (in percent). The NCL (Non-Critical Load) outlet on the rear panel shuts off based on the Low Battery NCL Shutoff setting. If the HTPC is connected to the NCL outlet, the user must be sure to set the Low Battery HTPC Shutoff value higher than the Low Battery NCL Shutoff setting. The Cold Start checkbox allows the UPS to start-up in the absence of AC power.
While most users will want to power off their projector immediately after power is lost, the design allows up to 5 minutes before any powerdown sequence begins. The advantage of this is if power is returned within this time period, the user can continue to view their video without interruption assuming all other components are powered. We happen to have a separate UPS for our HTPC, so this worked great for us.
Panamax has done an excellent job executing their MAX® 1500 UPS product and making it capable of controlling today's A/V components. Projectors with their costly internal lamps that require proper cooling when turned off will especially benefit from the new design. Failure to properly cool down the hot lamp can result in damage to the expensive bulb or projector. The design ensures the projector will shut down without user intervention. Panamax does not supply the IR flashers, so they must be purchased separately.
