UAP500A/1000A

UAP500A/1000A are AC sources. Provide low distortion sine wave output and measurement of power supply accuracy. Four windows LCD fully displays the measured data. Remote control can be completed via RS-232C. This series of power supplies can simulate normal and abnormal AC input conditions and measure the important electrical performance parameters of the object to be measured. It is applicable to electronic and motor industry, lighting, R & D, and quality inspection fields.

KEY FEATURES

Model
UAP500A

FEATURES

Four windows display

These two AC sources have four window display function. The requirement of simultaneous observation of multiple parameters can be realized. It saves time for parameter switching and reading

9 groups of presets

UAP500A/1000A provides 9 sets of parameter presets. Common parameters can be pre stored and quickly retrieved during use to improve test efficiency.

Remote control

UAP500A/1000A is equipped with RS232 communication interface. SCPI and MODBUS protocols are supported. You can use the upper computer provided by us for remote control, or you can write control programs freely and integrate them into your automation system.

Numeric keys

The power supply of this series has numeric keyboard, knob, and direction key, which can effectively speed up the speed of parameter setting and simple operation.

Delay output

UAP500A/1000A has the function of output delay to slowly raise the output voltage to the target value. Protect the tested products. It is very suitable for testing some surge sensitive products.

One key switching H/L voltage

This series of AC source has two voltage levels: high section and low section. One key switching high and low voltage output. Full range adjustable output voltage 0-150V / 0-300V.

Dual output

UAP500A/1000A is equipped with front and rear output sockets. You can freely choose front wiring or rear wiring according to the test environment.
