MECER 1000VA/800W (ME-1000-WPRU) Online Rackmount UPS
The MECER 1000VA/800W (ME-1000-WPRU) is a true double-conversion online UPS, built in a 2U rackmount form factor for server rooms, network cabinets, and other environments where equipment needs continuous, clean power rather than a brief battery bridge during outages. Unlike standby or line-interactive UPS types, an online UPS continuously runs connected equipment off its inverter, so switching to battery power during an outage happens with zero transfer time rather than a brief interruption. Output is a pure sine wave, matching the power quality of stable utility electricity, with voltage regulation held to ±1% and total harmonic distortion kept under 3% for linear loads. The unit ships with two 12V/9Ah batteries built in, providing a typical recharge time of about 4 hours to reach 90% capacity, and an LCD display shows load level, battery level, and operating mode at a glance. Management options include optional SNMP for network-based monitoring and Smart RS-232/USB connectivity, supporting a wide range of operating systems including Windows, Linux, and Mac.

Best Suited For
- Server rooms and network cabinets needing rack-mounted, continuous clean power for servers, switches, and networking equipment
- Businesses running sensitive electronics, such as PBX systems, CCTV DVRs, or POS equipment, where power quality matters as much as backup runtime
- IT environments wanting remote monitoring, given the optional SNMP and USB/RS-232 connectivity for tracking UPS status across common operating systems
Recommended Action: Confirm your equipment’s total power draw stays within the 800W capacity before deployment, and consider the long-run model with additional external batteries if extended runtime beyond the standard battery set is needed.
