Main features of analog remote control (based on the types and products)

What is most important thing about remote control of DC power supplies is to ensure the proper connection for installation as well as safe grounding that can achieve high performance, high stability, and low ripple with the device.

Remote switch (LS) It turns the output of the power supply ON/OFF from a distance.
Door switch (LD) The interlock function is provided for safe use.
Master/Slave As the control of the master unit is activated, the slave unit will follow suit that enables the output to increase.
Current source 1 mA It is provided to set the remote control value in the resistance mode.
Reference unit It is provided to set the remote control value in the voltage mode.
Fail-safe mode It maintains the safety of the wiring of control system using a reverse process if there is an abnormality like disconnection.

Remote Control

Remote Control Remote/Local control is selected.
Remote control of voltage (CV)
  • You can set between remote control and local control.
  • The remote control of voltage is available in the following two modes.
    1. Controlling using external voltage
    2. Controlling using external resistance
Remote control of current (CC)
  • You can set between remote control and local control.
  • The remote control of current is available in the following two modes.
    1. Controlling using external voltage
    2. Controlling using external resistance
Remote control by overvoltage protection
(OVP)		 The function is used for protecting the load against errors of programming and voltage setting, as well as abnormality of power.
Remote control by overcurrent protection
(OCP)		 The function is used to avoid troubles caused by errors of programming and voltage setting, as well as short circuit in the load.
Range switching As of output voltage, current, frequency, etc., the range is switchable. The settings depend on the models.

Monitor

Monitor It shows the output current and output voltage from 0 up to 10 V by changing the maximum output.

Status

OUTPUT The signal is issued while the power supply is working.
FLT
(The output is closed)		 When an abnormality is detected, the status is performed. The output is closed immediately when detecting abnormalities
including overvoltage, overcurrent, reverse connection of sensing, door switch, input voltage drop, differing in the models.
CV In constant voltage control, the signal is issued.
CC In constant current control, the signal is issued.
Local mode In the local mode, the signal is issued.
Remote mode In the remote mode, the signal is issued.
Overtemperature protection When an abnormal temperature is detected in the internal temperature of the power supply, the signal is issued.
OVP The overvoltage protection function is activated, the signal is issued.
OCP The overcurrent protection function is activated, the signal is issued.
AC input voltage abnormality The signal is issued when the input voltage drops.
Reverse connection of sensing The signal is issued when an error of sensing connection occurs.
Door switch OFF When the door switch becomes open, the signal is issued.
