Key Features
-
-
True online double-conversion topology – Ensures the load is always powered through the inverter (clean power) rather than just line interactive.
-
Wide input voltage range – The input accepts 110 VAC-288 VAC (for full load above ~176 VAC) and input frequency range 40-70 Hz.
-
Pure sine-wave output – Suitable for sensitive electronics (servers, telecom, data centre gear). High input power factor / low THD – Helps reduce input distortion and improves compatibility with utility power. For example, input PF ≥ 0.97.
-
Voltage regulation – Output voltage regulation ± 1% under specified load conditions.
-
Smart communication and monitoring interfaces – RS232 standard, optional SNMP, USB, dry contact, etc. Enables network monitoring/management of the UPS.
-
Cold-start capability – The UPS can be started from battery when mains power is off.
-
Compact design for tower installation – The HT11 series is designed for small-to-medium installations (IT rooms, edge computing) and supports built-in battery versions.
-
Overload / protection features – The device offers full protection for over-voltage, short-circuit, over-temperature, and supports defined overload margins.
