MCK 301-8X medium and deep refrigerating unit controller with automatic thawing is used to control freezer units, refrigerated counters, monoblocks and other commercial and industrial refrigerating devices.

The unit automatically maintains the freezer and evaporator temperatures as well as, depending on the mode of operation, either the second evaporator temperature or the temperature in the fan’s air flow.

If necessary, MCK-301-83 allows discovering and responding to the following emergencies:

  • Short circuit or sensor breakout
  • Leaving the unit door open for a longer time than allowed
  • Unacceptable deviation in voltage parameters
  • Sticking/welding of contactor output contacts
  • Unacceptable over range of the compressor temperature

Type: Digital

Output: 8A @ 250 V AC

Temperature Range: -45 to +50 deg C

Brand: NOVATEK-ELECTRO

Model Number: MCK-301

Additional Information:

  • Item Code: MCK-301
  • Port of Dispatch: New Delhi, India

Analog inputs: there are 3 inputs for NTC/PTC temperature sensors (temperature sensors of chamber)

A digital input can be used:

– to connect a door alarm sensor;

– to control defrost (the decision is made according to «closed/open» state);

– as an input for external alarm signal.

Main outputs:

-two-way break-before make relay output for the compressor control – 8A 250V at cos φ =1;

-a normally open relay output for the evaporator fan control – 8A 250V at cos φ =1;

-a normally open relay output for the electric heater control – 8A 250V at cos φ =1;

-an opto-triac output to start an alarm signalling – 60 mA 50Hz

Mounting position is arbitrary.
