HTU UPS

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 UPS features power factor corrected, sophisticated multi-stage charging, and pure sine wave output with a high surge capacity, meeting the 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 connected to utility power.

Another important feature of the HTU UPS is the customizable battery priority switch to extract maximum power from the batteries.
