Outline

The PAR Series are multi-function??A??Ahighly reliable CV/CC power supplies with built-in microcomputer and voltage remote sensing terminal. When a PAR Series power supply is incorporated in a system??A??Ait will be compatible with a variety of remote control capabilities including the GP-IB and computer control. Additionally??A??Athe built-in listener/ talker functions make these powerful??A??Amulti-function power supplies possible to implement systems expansion safely for automated measuring systems and simulation testing systems.

Features

●Remote Sensing The remote sensing terminal allows for compensation to handle the voltage drop caused by the impedance of leads for up to 1 V per path. ●Three Preset Voltages Up to 3 most frequently used voltage and current settings can be preset to allow speedy output switching with a press of a button. ●Output Protection The output is interrupted when a preset key or variable key is pressed so output of unexpected voltage or current can be prevented. (It is also possible to disable the output protection function.) ●Key Lock A key-lock function can be used to hold all setting values and invalidate the input of other keys than the power switch, thereby preventing the inadvertent changes of values during experiments. ●Simultaneous Display of Voltage and Current Output voltage and current are indicated simultaneously on 7-segment LED display to allow easy checking of the output values and setting values. ●Energy Saving Design The energy-saving design minimize temperature rise inside the unit, making a ventilation fan unnecessary, and thereby eliminating trouble such as noise, vibration and absorption of dirt. ●Simplified Operation The ease of operation is improved by adopting the one-touch button or rotary encoder control operations for the setting of keys and switches. ●EXT CONTROL Signal Output An open-collector signal is output for use in driving an external relay, etc. ●SPECIFICATIONS Model PAR18-5 PAR36-3 Output voltage Output voltage 0 to 18V 0 to 36V Setting resolution 10mV Maximum output voltage 18V 36V Model PAR18-5 PAR36-3 Output current Output current 0 to 5A 0 to 3A Setting resolution 10mA Maximum output current 5A 3A Model PAR18-5 PAR36-3 Voltage regulation characteristics (at times other than during voltage remote sensing operation) Line regulation (with respect to ±10% variation in AC) 2mV Load regulation (with respect to change from 0 to 100%) 5mV 4mV Ripple/noise (10Hz to 1MHz) 0.5mVrms Ripple peak (p-p) 5.6mVp-p 4.2mVp-p Transient response 100μs Typ Temperature coefficient 100ppm/°C Typ Model PAR18-5 PAR36-3 Current regulation characteristics (at times other than during voltage remote sensing operation) Line regulation (with respect to ±10% variation in AC) 4mA Typ 3mA Typ Load regulation (with respect to change from 0 to 100%) 20mA Typ 15mA Typ Ripple/noise (10Hz to 1MHz) 5mArms Typ 4mArms Typ Ripple peak (p-p) 10mAp-p Typ 8mAp-p Typ Temperature coefficient 200ppm/°C Typ Model PAR18-5 PAR36-3 Voltmeter Display (3-1/2 digits?
