REGULATED DC POWER SUPPLIES

The PS Series power supplies are DC constant-voltage (CV), constant-current (CC) power supplies based on the variable switching method, featuring compact size, light weight, excellent reliability and the variable outputs. They have been designed as highly universal stand-alone type models putting emphasis on the ease of operation and safety and equipped with a variety of protection functions. Three capacity types are available including 360W, 720W, and 1080W and 13 kinds of variations are available by combining ranges of 0 to 6 V, 10 V, 20 V, 36 V and 60 V. Several versatile applications are also provided including remote control functions with GP-IB control capability (which is possible when the optional GP-600 is used.)

Compact Size, Light Weight, High Efficiency

Thanks to the advanced switching method, the PS Series power supplies are both compact and light , with less than half the mass and volume of previous power supply models, resulting in an excellent space factor and high efficiency

.Digital Display of Voltage and Current

Output voltage and current are indicated on 7-segment red LED displays to allow easy checking.

Safety

(Fail-Safe Function)

For safety, the switching operation is stopped (output off status) and the AC power relay is interrupted while a protection function is operating.

●Output over-voltage protection (OVP)

When the output voltage exceeds the OVP setting value, the switching operation (oscillation) is stopped and the output is turned off.

●Output over-current protection (OCP)

Increase in the output current to 110% or more of the rated cur rent is detected by a protection circuit, which stops the switching operation and interrupts the AC power relay.

● Over-heat protection (OHP)

When the heat sink temperature reaches about 100℃ , the switching operation is stopped and the AC power relay is interrupted.

●Input power abnormality protection

In case of input over-voltage, input voltage drop or an over-current due to internal abnormality, the switching operation is stopped and the output is turned off.

●Alarm (power abnormality) signal

When the output over-current, input over-voltage or input overcurrent is detected, when the over-heat protection circuit is activated or when the power is switched off, an alarm signal is generated to turn the output off and interrupt the AC power relay.

●Power relay off signal

When trouble occurs on the user side, etc., the power relay is interrupted by an external signal.

(Rush current protection circuit)

The rush current protection circuit is activated at the moment of the power is switched on to reduce the input surge current.

GP-IB System Compatibility

In addition to the output voltage and current control capabilities and status signal outputs, the output on/off, power on/of f control and remote/local switches are provided. The GP-IB control is also possible optionally (when the optional GP-600 is combined.)

Wide Applications

Control operations include control by an external voltage or resistance of the output voltage and current.

Low Noise

The temperature-sensitive fan motor reduces the rotation speed when the load is light or the ambient temperature is low to prevent noise.

Front Air Intake

The forced air cooling system intakes air through the front panel and increases the packing density in case the power supply is mounted in a device or rack. The front grill incorporate an air filter to improve dust protection.

Power Switch

To enhance the safety of the power supply, the protect function based on an AC power relay is provided separately from the power switch. The AC power relay can be turned on/of f from a external signal while leaving the power switch in the on position.

Function

OVP Presetting

Pressing the OVP switch displays the OVP (Over Voltage Protector) trip voltage on the voltmeter. This lets you perform setting and verification without interrupting operation, even while the output is on.

Digital Display

A bright, easy-to-read red LED shows the voltage and current simultaneously. The voltage can be measured in 3-1/2 digits (autoranging) with a maximum display resolution of 10 mV with all models. The current can be measured in 3-1/2 digits (autoranging) with a maximum display resolution of 10 mA with models with rated currents below 50 A, and in 3-1/2 digits with a maximum display resolution of 100 mA with models with rated currents of 50 A or more (3-digit, 1 A resolution with the PS10-

210).

Output Switch

The output switch uses an electronic switch system to eliminate chattering or noise. The switch is set automatically to off when power is switched on so that unexpected output is not produced. The output can be fixed to on or the output on/off switching can be remote controlled with an external signal according to the DIP switch selection.

Limit Switch

Pressing the LIMIT switch displays the constant voltage setting value on the voltmeter and the constant current setting value (current limiting value) on the ammeter. This makes setting and verification possible without interruption, even while the output is on.

AC Power ON/OFF Control

The power protection device (AC power relay) can be controlled on /off from an exter nal signal (provided that the power switch is on).

CV/CC Monitoring

●A monitoring output from about 0 V to 1/10 the rated voltage can be output with respect to the output voltage from 0 V to the rated voltage.

●A monitoring output from about 0 V to 10 V can be output with respect to the output current from 0 A to the rated cur rent.

Control by an External resistance of Output Voltage and Current

Remote Sensing

This function prevents the voltage drop which is caused by the load connection resistance and the stability degradation caused by the contact resistance, and compensates for the voltage drop of up to 1 V per path provided that the output terminal voltage is within the rated voltage.

Output ON/OFF Control

The output can be turned on/off with an external signal. The output can also be fixed to on while power is on.
