Kenwood PA-B Series
Regulated DC Power Supplies
Models PA18, PA36, PA80, PA250

• Low-noise/low-ripple
• CV/CC power supply
• Series/parallel operation
• Floating output
• Full remote control
• Rack-mount size
• 3 Year Warranty
• GP610D GP-IB Adaptor Option

Designed to be both compact and provide high performance, the PA-B Series of series-regulated CV/CC power supplies have been developed to offer high reliability and stability, and to provide simultaneous digital display of both output voltage and current.  The product line includes the 18V, 36V, 70V, and 250V models to allow selection according to individual needs.  The output can be boosted by single-control series and parallel connections, and remote control enables easy use of these compact, lightweight power supplies in applications such as R&D, aging and as systems power supplies.

Product Information
Ordering Info

Low Ripple, Low Noise

Series regulation achieves extremely low ripple and noise, as well as a very low temperature coefficient and excellent electrical characteristics.

Simultaneous Digital Readout of Both Voltage and Current

Voltage is displayed on a 3-1/2 digit LED display (auto-ranging) and current is displayed on a 3-digit LED display, enabling checking and setting of both voltage and current simultaneously.  Constant-voltage and constant-current operations are indicated by green and red LEDs, respectively.

Series Operation, Parallel Operation

Several power supplies can be connected in series to boost output voltage capability, or in parallel to boost output current capability.  In addition, with either connection method, master-slave mode of operation enables you to control the output from just one of the connected supplies. 

Floating Output Method

Because the output terminals are floating, operation is possible as either a positive or a negative power supply.  Output sensing terminals are provided on the front panel for precise setting of the voltage actually applied to the load terminals.

OUTPUT ON Fixing

By setting the REMOTE/LOCAL switch on the rear panel to REMOTE, the OUTPUT key is isolated so that the output can be fixed to on while the power is on.  Usually, the output can be switched on and off using the switch on the front panel.

Wide Remote Control Capability

A remote control connector is provided on the rear panel, enabling external contact-closure signals to perform the output on/off control.  In addition, the output voltage and current can also be controlled by either an external voltage or resistance.

GP-IB Capability (Optional)

By using the GP610D GP-IB adaptor, GP-IB control of the output on/off status, the output voltage and the output current is possible.  Also, by incorporating the OP31A in a power supply of the PA-B Series, it is possible to control the output on/off status and SRQ function.

Applications

• R&D
• Aging
• Systems
• Battery Charging
• School and Education

Remote Sensing

This function compensates for the voltage drop at the load terminals which is caused by resistance of leads between the PA-B Series supply output terminals and the load and by output terminal contact resistance. (The use of the provided sensor plug is required.)

Control By An External Resistance

An externally applied resistance (0 to 10 kW) can be used to control the output voltage and current.

Single-Controlled Parallel Operation 

It is possible to connect power supplies of the same model of the PA-B Series in parallel to increase the output current capacity.  One unit (the master) can be used to control all the other units (slaves) in a master-slave setup.

Parallel Connection

Any power supplies of the PA-B Series can be connected in parallel by setting their output voltage to the same value.

OUTPUT ON/OFF Control

It is possible to ON/OFF control the output using an external contact-closure signal.

Control By An External Voltage

An externally-applied voltage (0 to 10V) can be used to control the output voltage and current.

Single-Controlled Series Operation

It is possible to connect power supplies of the same model of the PA-B Series in series to increase the output voltage capacity.  One unit (the master) can be used to control all the other units (slaves) in a master-slave mode of operation.

Series Connection

Series connection of any members of the PA-A Series is possible, up to the groundable voltage limit of 250V.

GP-IB Control

Used in combination with the optional GP610D GP-IB adaptor, the PA Series can be GP-IB controlled from a computer.
