Detailed Description

Msk-301 is designed to control freezers, refrigerating counters, monoblocs and other refrigerating s
Msk-301 is designed to control freezers, refrigerating counters, monoblocs and other refrigerating shop and industrial equipment. Msk-301 allows to monitor freezer and evaporator temperature and also, depending on a specified mode of operation, to monitor the second evaporator temperature or fan air stream temperature. The device permits to start automatic defrost at temperature difference between refrigerating chamber and fan air stream. Msk-301 can perform protective compressor cut-out if ptc- or ntc-type temperature sensor of compressor is connected to msk-301. Msk-301 provides safety compressor and fan stop under abnormal supply line parameters(it is performed monitoring of rms phase voltage and line voltage, phase imbalance, correct phase sequence and power contacts state of external magnetic starter before and after compressor cit-int) and also performs a consequent automatic reset when voltage parameters regenerated with time delay set by user. 2. Main features 2.1. Analog inputs: There are 3 inputs for ntc/ptc sensors with reinforced electric insulation for temperature monitoring and defrost control. 2.2. Digital input: Can be used for door alarm sensor connection or defrost control(the decision is made according to close/open state). 2.3. Main outputs: Two-way break-before make relay output for the compressor control A normally open relay output for the evaporator fan control A normally open relay output for the electric heater control An opto-triac output to start an alarm signalling - 60 ma 50hz. 2.4. Temperature resolution - 0.1c. 2.5. Voltage trip threshold setting accuracy is no more than 3v. 2.6. Nominal supply voltage: One-phase voltage is 220v 50hz or three-phase voltage is 380v 50hz. 2.7. Voltage range that guarantees safe msk-301 operation:160v - 330v. 2.8. Power consumption is no more than 5wt. 2.9. Apparatus protection degree is ip40. 2.10. Terminal block protection degree is ip20. 2.11. Operating temperature range is -45c - +55c. 2.12. Storage temperature range is -45c - +75c. 2.13. Weight is no more than 3kg. 2.14. The mounting - on the standard 35 mm din-rail. 2.15. Mounting position is arbitrary. 2.16. Operating controls and the dimensions of the device
