Kenwood regulated dc power supply, 0-18 volts, 0-3 amps


Kenwood PA18-3A Regulated DC Power Supply 0-18 Volts / 0-3 Amps
* Simultaneous Digital Readout of Both Voltage and Current
* Series Operation, Parallel Operation
* Wide Remote Control Capability
Designed to be both compact, and to provide high performance, the PA-A 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.
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.
Because the output terminals are floating, operation is possible as either a positive or negative power supply. Output sensing terminals are provided on the front panel for precise setting of the voltage actually applied to the load terminals.
By setting the LOCAL/REMOTE 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.
