Outline

The PD-A/AD Series power supplies are DC constant-voltage (CV)??A??Aconstant-current (CC) power supplies with variable output level featuring the use of the phase control method and high reliability. Inheriting the reliability and accuracy of the highly approved PD Series and incorporating a wide variety of protection facilities??A??Athe PD-A/AD Series power supplies have been designed with emphasis on the ease of operation and safety in use as research and experiment power supplies or long aging system power supplies. With 9 combinations of different voltage/current capacity values and the meter indication type and digital indication type models available for each of them??A??Aa total of 18 models offer a wide variation which can be selected according to applications.

Features

●High Stability, Large Capacity A unique phase control method which uses a built-in pre-regulator ensures fast response and efficient high-stability supply of high currents. ●Low Ripple, Low Noise The unique phase control method is combined with a choke-input type smoothing circuit to provide excellent input and load variation rates, low ripple and low noise. ●High-Accuracy Voltage and Current Settings The output voltage as well as the output current can be set using 10-turn potentiometers, enabling smooth, fine setting. ●Remote Sensing This function compensates for the voltage drop at the load terminals which is caused by resistance of leads between the PD-A Series supply output terminals and the load and by output terminal contact resistance. ●Remote Control The output voltage and current can be controlled by means of an external DC voltage or resistance. In addition, it is also possible to remote control the OUTPUT on/OFF by means of a contact switch. ●Voltage/Current Limiting A V/I CHECK switch is provided to allow setting the constant voltage and constant current setting values. The voltage and current values can be set and checked even while the output is on. ●Parallel Operation By connecting the PD-A Series power supplies of the same model in a master-slave configuration, a single master can control all of the slave supplies. This parallel operation makes it possible to increase the output current. ●Series Operation The output voltage can be increased by series connection. A series connection in the master-slave mode of operation is also possible, with which a single master can control all of the slave supplies (provided that the allowable grounding voltage is within ±250 V.) ●GP-IB System Compatibility The voltage and current can be set with high accuracy through GP-IB by connecting the optional GP-610D GP-IB adapter. The OUTPUT on/OFF can also be controlled through the GP-IB if the OP-12 EXT I/O unit (factory option) is added. ●GP-IB System Compatibility The voltage and current can be set with high accuracy through GP-IB by connecting the optional GP-610D GP-IB adapter. The OUTPUT on/OFF can also be controlled through the GP-IB if the OP-12 EXT I/O unit (factory option) is added. ●OUTPUT on/OFF The OUTPUT switch allows you to turn the output voltage on and off electronically. This can also be controlled externally by means of a contact switch. ●OVP (Over-Voltage Protection) The OVP protects the load from excessive voltage by switching the power off instantaneously in cases of operational mistakes or unexpected accidents. The OVP setting voltage can be displayed by pressing the OVP CHECK switch, and the setting can be made using a semi-fixed potentiometer on the front panel. The OVP setting voltage can be set or checked even while the output is on, without interrupting the use of the power supply. ●OCP (Over-Current Protection) The OCP protector circuits detects output current level above about 120% of the rated current and switches the power off. ●OHP (Over-Heat Protection) The OHP protector circuit detects the rise of heat sink temperature at about 100degree C and switches the power off. ●OHP (Over-Heat Protection) The OHP protector circuit detects the rise of heat sink temperature at about 100degree C and switches the power off. ●LED Indicators The green LED lights during constant-voltage operation and the red LED lights during constant-current operation. ●Output The output is supplied from 3 terminals based on the floating method. ●SPECIFICATIONS Model PD18-10A/10AD PD18-20A/20AD PD18-30A/30AD PD36-10A/10AD PD36-20A/20AD PD56-6A/6AD PD56-10A/10AD PD110-3A/3AD PD110-5A/5AD Output Output voltage 0 to 18V 0 to 36V 0 to 56V 0 to 110V Output Current 0 to 10A 0 to 20A 0 to 30A 0 to 10A 0 to 20A 0 to 6A 0 to 10A 0 to 3A 0 to 5A Model PD18-10A/10AD PD18-20A/20AD PD18-30A/30AD PD36-10A/10AD PD36-20A/20AD PD56-6A/6AD PD56-10A/10AD PD110-3A/3AD PD110-5A/5AD Voltage regulation characteristics Line regulation (with respect to ±10% variation in AC) 0.005% 1mV Load regulation (with respect to change from 0 to 100%) 0.005% 1mV 0.005% 2mV 0.005% 1mV 0.005% 2mV 0.005% 1mV 0.005% 2mV 0.005% 1mV Ripple/noise (10Hz to 1MHz)(typical) 0.5mVrms 1mVrms Transient response 50μs 100μs 50μs 100μs 50μs Remote control resistance/voltage 0 to 10kΩ/0 to 10V Model PD18-10A/10AD PD18-20A/20AD PD18-30A/30AD PD36-10A/10AD PD36-20A/20AD PD56-6A/6AD PD56-10A/10AD PD110-3A/3AD PD110-5A/5AD C urrent regulation characteristics Line regulation (with respect to ±10% variation in AC) 1mA 5mA 1mA 5mA 1mA 3mA 1mA Load regulation (with respect to change from 0 to 100%) 5mA Ripple/noise (10Hz to 1MHz)(typical) 3mArms 10mArms 3mArms 10mArms 2mArms 3mArms 1mArms Remote control resistance/voltage 0 to 10kΩ/0 to 10V Model PD18-10A/10AD PD18-20A/20AD PD18-30A/30AD PD36-10A/10AD PD36-20A/20AD PD56-6A/6AD PD56-10A/10AD PD110-3A/3AD PD110-5A/5AD P rotective circuit Temperature detection Approx. 100°C (power is shut off) Over-voltage protection 15% to 110% of rated output voltage (power is shut off) Input fuse rating (AC 100V/200V) 7A/4A 15A/8A 20A/10A 12A/6A 20A/10A 10A/5A 15A/8A 10A/5A 15A/8A Model PD18-10A/10AD PD18-20A/20AD PD18-30A/30AD PD36-10A/10AD PD36-20A/20AD PD56-6A/6AD PD56-10A/10AD PD110-3A/3AD PD110-5A/5AD Meter and display A type Voltmeter (2.5%) F.S. 18V 36V 56V 110V Ammeter (2.5%)F.S. 10A 20A 30A 10A 20A 6A 10A 3A 5A AD type Digital voltage display 3-1/2 digits, 19.99V, 199.9V (F.S.) two automatically switched ranges ± (0.1%rdg 1digit) 23°C±5°C, PH80% or less Digital current display 3 digits or 3-1/2 digits, fixed range ±(0.5% of rdg 1 digit) 23°C±5°C, PH80% or less 19.99A(F.S.) 99.9A(F.S.) 19.99A(F.S.) 99.9A(F.S.) 99.9A(F.S.)
