Rack-mount UPS for critical equipment

The PANAMAX MB1500 delivers 1500 VA and 900 watts of true sine-wave backup power through four AC outlets. It accepts an input range of 85 to 137 volts at 47 to 63 hertz and regulates output to 120 volts within five percent. Battery run-time is 12 minutes at full load or 30 minutes at half load, while non-sacrificial AVM surge protection and LiFT noise filtration guard connected gear.

Installation notes and common issues

The unit measures 4.00 by 19.00 by 17.00 inches and weighs 72.5 pounds, so two-person rack mounting is advisable. USB and RS-232 ports provide management access, and a BlueBOLT IP card can be added for remote control. Dual learning IR outputs allow programmable outlet-group sequencing, but the optional BATT1500-EXT battery pack is required for extended runtime.

Pre-purchase checklist

Confirm your rack supplies 19-inch mounting rails and can support the weight. Verify that the connected load stays within 900 watts and that the 120-volt output matches your equipment. Ensure the input circuit operates between 85 and 137 volts at 47 to 63 hertz. Buyers needing longer runtime than 30 minutes at half load or more than four protected outlets should consider additional battery packs or a higher-capacity unit.

Questions about this item

How do I confirm the PANAMAX MB1500 is delivering true sine wave output after installation?

The unit produces a 120 V output with a tolerance of plus or minus 5 V and a 60 Hz frequency held within 1%. Its true sine wave output and AVM automatic voltage monitoring maintain regulated power; the front-panel display and USB or RS-232 interface report real-time voltage and frequency so you can verify the waveform is stable.

What ships with the MB1500 and which expansion items are sold separately?

The rack-mount UPS includes four programmable AC outlet groups, a USB port and an RS-232 port with open-source protocol. A BlueBOLT IP card for remote internet control and a BATT1500-EXT battery extension pack for longer runtime are optional accessories that must be purchased separately.

Which runtime option suits my load — the standard battery or the extension pack?

At the full 900 W load the internal battery provides 12 minutes of backup; at half load it provides 30 minutes. If your equipment requires more than 30 minutes at reduced load or any additional time at full load, the BATT1500-EXT extension pack (sold separately) is the only way to increase those figures.
