Telecom AC Cum ATM Controllers

Product Details:

• 48 VDC operated. Dual AC controller with free & emergency cooling
• AC fail alarm. Compressor fault sensing. (HP, LP)
• Over Current & Undercurrent sensing for compressor
• Internal swapping to maintain equal run-hours
• RS485 / RS232 connectivity (optional)

• 2 NTC for Ambient and Shelter temperature, 1 Humidity sensor
• Digital Inputs: HP, LP, UL, OL, MCB1, MCB2, DC fan fault sensing
• Digital output: DC Fan 1, DC Fan 2, Compressor 1, Compressor 2, Damper 1, Damper 2, Ac 1 fail alarm, Ac 2 fail alarm, HT alarm

Product Details:

• This is a two-compressor controller with an inbuilt Free Cooling Capability.
• It is specifically designed to maintain the Shelter temperature at a desired level with the help of Compressors or by using Free cooling concept at low ambient to save energy.

Product Details:

• The CRC - 1200 is a panel/wall mounted controller dedicated to controlling the cold room and its various devices.
• The controller controls the defrost in the system based on either an electrical heater where the compressor is stopped, or at cycle inversion using warm gas where the compressors keeps on working.
• It is also possible to select the interval between defrosts and a maximum time out after which the defrost is interrupted.
• The same probe which controls the defrost cycle is also used to control the evaporator fans.
• Post drip and condenser fan control are amongst many other features in this controller.

Additional Information:

• Item Code: CRC-1200

Product Details:

• Innovation is our forte and we strive to design and develop a precision engineered range of highly efficient Cold Room Controllers.
• This CRC-1100 is a panel mounted controller and is efficient in controlling the cold room temperature. There is a controller present in these freezers, which effectively controls the defrost.
• It does so either with the aid of an electrical heater where the compressor is stopped or at cycle inversion using warm gas where the compressor keeps on working.
• Intervals between defrosts and the maximum time out after which the defrost needs to be interrupted can be decided by the user.
• Evaporator fans present in the freezer are controlled by the same probe which controls the defrost cycle.

Other Details:

• Possible to set the temperature
• Delay time after a defrost can also be set
• User can also decide the relation of fans with the compressor

Main Features:

• LCD with back lighting to display all parameters
• 2 NTC probes for cold room temp + evap. coil temperature
• Relay outputs: Compressor + Cond. Fan + Heater + Evap. Fan + Alarm
• Audible alarm.
• Digital inputs: 2 nos. (a) Door switch (b) Pressure cutout
• HP / LP / OSS trip protection for compressor.
• Compressor protection algorithm
• Auto/Manual defrosting facility (Time/Temp based)
