Description
Direct Supply BRAND NEW PARTS refrigerators, cold storage evaporators, and air conditioning equipment. It is used in conjunction with electronic expansion valves (such as ETS series) to achieve precise adjustment of evaporator superheat and optimize refrigeration efficiency. Core functions : Superheat control : By receiving signals from temperature sensors (such as Pt1000) and pressure sensors (such as AKS33), it calculates the evaporator superheat in real time and uses a PID adjustment algorithm to control the opening of the electronic expansion valve. This ensures that the superheat remains within the set range (usually customizable to 5-10℃), preventing liquid carryover in return gas or excessive superheat. Protection mechanisms : Equipped with Maximum Operating Pressure (MOP) protection to prevent compressor overload due to excessively high suction pressure; supports alarms for sensor faults (such as disconnection, short circuit) and abnormal drive of electronic expansion valves, enhancing system safety. Control logic : Can be started/stopped via external switch signals and supports remote reset, adapting to the integration needs of automated control systems. Input and output specifications : Temperature input: Supports 1-2 Pt1000 temperature sensors (measurement range is usually -50℃ to +100℃) for monitoring evaporator outlet temperature and ambient temperature. Pressure input: Compatible with Danfoss AKS33 series pressure sensors (4-20mA signal) to monitor evaporator inlet or suction pressure, assisting in superheat calculation. Output signal: Pulse signal drives the stepper motor of the electronic expansion valve (output current is approximately 100mA), adapting to the flow adjustment needs of ETS series electronic expansion valves. Alarm output: 1 SPST relay output (contact capacity is usually AC250V/3A) for fault alarm linkage (such as sound and light alarm, system shutdown). Power supply and environment : Power supply voltage: AC 24V ±15%, 50/60Hz, power consumption is approximately 5VA (including electronic expansion valve drive). Operating environment: Temperature -10℃ to +55℃, humidity 20%-80%Rh (no condensation), protection class IP20, suitable for installation in control cabinets. Installation and configuration : Installation method: DIN rail mounting, compact structure (size approximately 100×60×30mm), saving installation space. Parameter setting: Adjust parameters such as superheat set value, MOP threshold, and alarm delay through dedicated programming tools (such as Danfoss Toolkit) or panel buttons (supported by some models), ensuring convenient operation. Differences from Same-Series Models Both EKC315A and EKC312 are superheat controllers, with the core differences being: EKC315A further optimizes superheat adjustment accuracy, especially with faster response speed to variable load conditions (such as frequent door opening/closing of refrigerators), making it suitable for scenarios with higher requirements for temperature control precision. Some versions of EKC315A support more sensor connections (such as condensing temperature monitoring), enabling more complex linkage control logic.
Overall, we had a good experience with the seller We purchased item "1PCS NEW ABB Type AX18-30-10-84 Block Type AC Contactor 110V 50Hz" There was a mix up with our tracking number and another customer's tracking number in the beginning, but this was figured out in a timely manner Then the courier service attempted to deliver our package, but it was after our business hours, so they did not deliver the package on the day it was expected Eventually, items received Have not used items yet
Slight mix-up on the quantity of the order but the seller was very responsive and immediately sent the balance of the propellers ordered along with a sincere apology. Mistakes happen and this seller dealt with it like a professional! I would gladly do business with plc-electric again in the future. Thank you!
Quality new condition perfect value excellent appearance identical this guy got the colour right for me not like some some don’t care and they try to palm you up with anything this guy didn’t he supplied me with what I asked for and I received what I asked for A1 to this guy
