The HTU UPS is a durable, high operating temperature UPS, ideal for outdoor applications. It is a combination of an inverter, battery charger and AC transfer switch in one complete system with a peak conversion efficiency of 88%. It has an overload capacity of 300% for 20sec to support tools and equipment longer.
The HTU features power factor corrected, sophisticated multi-stage charging and pure sine wave output with a high surge capacity, meeting power needs of inductive loads without exceeding equipment limitations.
When AC utility power is lost the transfer relay is de-energised and the load is automatically transferred to the UPS output, conversely, once the utility power is restored and voltage is within the UPS range, the relay is re-energised and the load is automatically connect to utility power.
Another important feature is the customizable battery priority switch to extract maximum power from the battery/s.
