Outline

The PR-A Series of series-regulated CV/CC power supplied were designed to provide a compact power supply package with high performance??A??i and ensure excellent reliability as well as excellent design. Seven types are available for a variety of requirements??A??i three 18 V types??A??i two 36 V types??A??i one 70 V type and one 250 V type. Whether used individually or connected in series or parallel for greater capacity??A??i the PR-A Series ensures excellent performance. These power supplies are housed in a compact rack-mount package and can be used on the bench top as well.

Features

●Low Ripple, Low Noise Series regulation achieves extremely low ripple and noise, as well as a very low temperature coefficient and excellent electrical characteristics. ●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 the parallel connection method, master-slave setup lets you control the output from just one of the connected supplies. ●OUTPUT on/OFF Switching The output can be switched on and off with a switch on the front panel. ●CV/CC LED indicators The green LED lights during CV operation and the red LED lights during CC operation. ●Floating Output Method Because the output terminals are floating, operation is possible as either a positive or negative power supply. ●PR-A Series Parallel-Connected Operation It is possible to connect several of the same model of PR-A Series power supplies in parallel to increase current capability. Output is controlled from one master unit. ●PR-A Series Optional Equipment ■Rack Mount Adapter for PR-A Series  RK-604E (EIA) External Dimensions (Unit: mm) ■Blank Panel RB-604A (1/2 rack width) RB-604B (1/3 rack width) RB-604C (1/4 rack width) RB-604D (1/6 rack width) RB-604E (1/12 rack width) ●Applications ?
