EPEC100/200 series power environment controllers

Summary&application:

EPEC100/200 series power environment controllers are used in terminal boxes, power boxes, mechanism cases, electrical boxes, etc. places where needs real-time monitoring the temperature and humidity of environment. Acquisition and display of the load field temperature & humidity signals, setting of the control parameters, acquisition of gate travel signal, acquisition of fog signals, heating dehumidifier and fan control system, with RS485 module and transmitting output module to realize the remote of the data.

 

1. Main  functions and characteristics:
◆It can measure the temperature & humidity of box  environment. When the environment temperature is too low or the humidity is too  high, it will automatically start the heaters to heat and dehumidify; when the  environment temperature is too high, it will automatically start the fans to  cool down.
◆It can measure the oil temperature of the oil-filled  transformer, and give out over temperature alarm and over temperature trip  signals.
◆It has fog alarming function.
◆It has several indicator lights, separately indicating  the temperature and control state.
◆Optional for environment temperature transmitting output  module, with -40.0℃~80.0℃ corresponding for 4~20mA output.
◆Optional for RS485 communication module, with baud rate  of 2400~19200 to be chosen.
◆Optional for gate interlock trip function.
