The capUPS are a series of no-battery UPS systems that use super capacitors rather than conventional batteries. The advantage is that they charge very quickly and that they are able to be recharged 500,000 times. This is beneficial for applications that that have either a large number of battery discharge cycles or where a "maintenance free" solution is required such as remote terminals or mobile data collectors.

The capUPS products come in capacities of 250 and 500 Farads and can supply back-up power to a twenty Watt load for 22.23 minutes through 44.47 minutes respectively. The input power range is 5V to 32VDC at up to 12A. The output voltage is programmable from 5V to 24VDC. The output current is 12A when output is working in "buck" mode and 5A when working in "boost" mode. Switch-over from buck to boost is automatic when the capacitor terminal voltage is above or below the set output voltage. The output voltage and low capacity levels are non-volatile and field programmable via an onboard serial port and LAN. Status lights on the front panel indicate operational status. The capUPS systems have an operating temperature of -40° to +65°C and are passively cooled and housed in a rugged .125" extruded aluminum enclosure that provides a dual system of both shock and vibration isolation.
