ZTM Series Modular UPS
The ZTT ZTM Series is a fully digital 3-phase modular online double-conversion UPS. Modules and cabinets are combined to cover 10 kVA to 2000 kVA. All variants share: online double conversion, output PF 1, high reliability with component-level protection, intelligent self-diagnosis with large history-record storage, 7" or 10" touch LCD with IoT functions, and USB / RS232 / RS485 / dry-contact interfaces (SNMP, AS400, parallel kit, SPD, LBS optional). The 380/400/415 V family scales to 2.0 MVA — the reference solution for mega data centres. Dedicated 480 V (60 Hz) and 208 V (60 Hz) variants are provided for North-American and low-voltage distribution.
