The PW-A Series are multi-output tracking CV/CC power supplies featuring a built-in microcomputer and excellent reliability. PW-A Series provides a multi output and a great function, and can be used from the development to the manufacturing by mounting the interface (factory option) for computer-controlled. There are two kinds of interfaces for computer-controlled, and corresponds to a full remote with listener and talker function. IF-40GU can be controlled with GP-IB or USB, and IF-40RS can be controlled with RS-232C.
All setting conditions are selected at the single rotary-encoder. Speedy setting is available to select the figures by the digit-key. Output voltage and current can be set to resolutions of 10mV at 18V/ 36V output, 1mV at 6V/8V output and 1mA.
Output voltage and current value of positive and negative can be adjusted from zero at the same time by the absolute value tracking. And adjusting plus % and minus % value based on a certain voltage and current value is possible. The trucking function can be disabled for individual adjusting of positive and negative value.
4 Points Pair Presetting of Voltage and Current Value
Four sets of frequency used voltage and current can be preset. (V-A pairs) It is possible to quick set-up. A variable adjustment is also available.
ON/OFF Delay Time
Delay-time can be set in each output. For multiple-output power supply, When multiple-output is turned on or off at the same time, the equipment is occasionally damaged. For this, the time of on and off of a specific output can be delayed.
On and off of each output can be selected and set besides the main output key.
A key lock function provides to hold all setting values excepting power switch. It prevents the miss-operation.
Limit & Status
The output voltage and current values can be confirmed by the limit-key. The trucking of each output and the condition of delay setting can be confirmed by the status-key.
Various External Controls
ON/OFF of main output, selection of PRESET1-4 and makes to the alarm and a main output is turned off.
When the exhaust temperature enters the state of overheating, the alarm signal is output and a main output is turned off. When the alarm signal is output in case of one of several systems, all main outputs are automatically turned off. Maximum 5 sets can be connected.
Heat Radiation Method
Rotation speed of the fun is proportion to the temperature of exhaust air. It was considered to the noise.
