AX-PPR3-105 - Three Phase 105kW Thyristor:
The AX-PPR3-72 and AX-PPR3-105 Power Regulators are designed to provide continuously adjustable control of electric heating loads from a BMS Controller or similar. Applications include electric heating coils, heating cables and electric furnaces. The AX-PPR3 Series use solid-state switching with “zero crossing technology” to minimise RFI and provide accurate switching control. All Power Controllers in this series feature Over Temperature Protection with automatic reset and Alarm Output, LED Indication of Output ON and are designed for panel mounting. The AX-PPR3-72 and AX-PPR3-105 feature an integral cooling fan which turns on automatically when required. No additional heatsinks or fans are needed.
