PFN220-150EST PFN220 1/2 Hp – Electronic Voltage Protector Module for Refrigerator’s Manufacturers 220V 15A 1/2 H.P.

The BREAKERMATIC PFN220 1/2 HP is an electronic voltage protection module designed to be incorporated as an original part in refrigeration equipment, capable of handling refrigeration compressors up to 1/2 HP. It protects against blackouts and high and low line voltages, interrupting power when an abnormal condition is detected.

The PFN220 1/2 HP connects using spade type, quick connect terminals, making it easy to incorporate into the production line with prefabricated connection harnesses.

Three LED indicators allow us to check the status of the protector.

Ideal for

• Refrigerators
• Freezers
• Refrigerated display cases
• Bottle racks
• Beverage displays

Operation

Protection against steady-state voltage variations.

The PFN disconnects the output if the steady-state voltage is above the high cut-off voltage or below the low cut-off voltage indicated in the specifications. The response time to a fault is typically 1.5 s. The voltage must remain outside the range longer than the response time for the disconnection to be activated. While the fault is present, the voltage fault indicator will remain illuminated.

Reconnection delay or standby cycle.

When the protector is energized, or at the end of a voltage failure, the protector will initiate a time delay before connecting the output. The duration of the time delay is indicated in the specifications. The standby cycle protects sensitive equipment from short operating cycles, allowing, in the case of A/C and refrigeration equipment, system pressures to equalize before reconnecting. While the output is off, the wait cycle signal will remain on. Once the wait cycle ends, the output is activated, the wait cycle indicator turns off, and the normal voltage indicator turns on.

Autostart.

This feature reduces the standby cycle to 5 seconds when the protector has been off for a considerable amount of time.

Blackout and brownout detection.

The protector will disconnect the load if it detects a sudden voltage drop below 50% of the nominal voltage and initiate a standby cycle. The blackout detector responds instantly when the criteria in the specifications for the minimum blackout duration are met.
