Display & Programming overview. HPL110 Unipower Version 4.0 Technical Information English Edition Technical Specifications Electrical Voltage Range The HPL110 is programmed by the use of only three keys located at the front panel. See See Technical info on the unit paragraph about programming on page 2. The parameters and their programming ranges are Also availible: listed in the table above. Parameters are stored in EEPROM. When no key has been activated for 3 x 120 VAC -> 3 x 575 VAC about 5 seconds the display returns to the kW % position. Note that the function of the keys is Current Range repeated if continuously activated. Internal: max. 8 Amp. External: N/1 or N/5 converter. Cos Range::::: 0-1 LED usage: Frequency Range: 45-65 Hz.

The HPL110 integrates a Max. and/or a Min. kW limit detector plus the support functions necessary to establish the efficient and compact supervision or regulation of various types of machinery such as pumps, ventilators and conveyer belts. The HPL110 has a built in current converter that works up to 8 Amp.
