Master/Slave

Master/slave is a function that allows the slave device to follow the operation of the master device. When the master device is controlled, the slave device follows and performs the same operation. By connecting the output terminals of the power supply in series or parallel, it can be controlled as a single power supply with increased voltage and current outputs.

1 mA current source

The 1 mA current source is a precision constant current source to control the set value of the output in resistance mode.

Reference voltage

There are two types of reference voltages: internal and external. The internal reference voltage is output from the analog remote terminal, and the output can be controlled by connecting an external resistor. The other external reference voltage provides another reference power supply, and its output is input to the analog remote terminal to control the power supply output.

Fail-safe mode

Fail-safe mode is a mode in which the logic of the control is inverted to ensure safety even in the event of a control wiring malfunction such as wire breakage.

Common (COM)

Common is a shared connection point, which is a potential that serves as a signal reference. Or, it is the common ground.
Depending on the power supply, the common of the analog remote control terminal may be a positive common connected to the positive output terminal or a negative common connected to the negative output terminal.
For more information, please see Matsusada Precision's FAQ: "What is the positive or negative common of an analog remote control?"

Retern (RTN)

Return refers to the return destination of a signal output. It is used to describe the terminal to which the output returns through the circuit to which it is connected.

Relay

A relay is an electromagnetic relay, which is connected to a device to transmit a signal.

TTL

TTL stands for Transistor-Transistor Level and represents a signal standard.

Open collector

Open collector refers to the signal output method of electronic circuits. The collector of the transistor becomes the output terminal.
For more information about open collectors, please see Matsusada Precision's FAQ: "What is an open collector in a power supply?"

Variable resistor

A potentiometer is a type of variable resistance that can be changed to any resistance value. It is used in variable resistors for analog remote control because the resistance value can be set finely. It is also called a volume potentiometer or pot.

Output state auto recovery prevention (Previous: power failure protection)

The Output state auto-recovery prevention is a safety function that prevents output when the power supply is in an output state and the input power supply is cut off due to a power failure or the like and then returns.
