Description

Must EH55-H1KS 1KVA 1KW Long Backup Online UPS

The Must EH55-H1KS is the long-backup version of the 1KVA / 1KW EH55 online UPS. If you are looking for a Must EH55-H1KS 1KVA online UPS price in BD, note that this model is sold without batteries: it is made to run from an external 36VDC battery bank, so you can choose a larger capacity for longer runtime.

Key Features

  • 1KVA / 1KW rated power with an output power factor of 1
  • Double-conversion online design with zero transfer time to battery
  • Wide input range of 110V to 300V AC
  • Runs from an external 36VDC bank of three 12V lead-acid batteries (not included)
  • High-current charger, 5 A by default and adjustable from 1 to 12 A
  • LCD display with four buttons and four LEDs
  • RS-232 and USB communication, with an optional SNMP, AS400 relay or RS485 card

Why choose a long backup model

A standard online UPS has a small built-in battery that covers only a short outage. When the power cuts last for hours, the battery bank has to be larger. The EH55-H1KS leaves out the internal batteries and adds a stronger charger so that external batteries can be recharged in a reasonable time. The batteries are bought separately, and the amp-hour rating you choose sets the backup time.

Input, output and protection

The UPS accepts 110V to 300V AC input at 50/60 Hz and delivers a regulated 208/220/230/240V AC output with ±1% accuracy. The load runs from the inverter at all times, so surges, dips and frequency changes on the mains do not reach it, and the transfer to battery takes 0 milliseconds. In AC mode, overloads are carried in stages, for example 30 minutes at 102 to 110% load.

Before you buy

Check the battery type, number and wiring with a technician before you connect a battery bank, because the bank must match the 36VDC system voltage. Noise is 45 dB or lower, and the operating range is 0 to 40°C and 20 to 95% non-condensing humidity.
