Portable Three Phase Power Source UTI

Can be externally controlled by computer through RS232 setting the parameters on computer and then test by control software; can be used independently also can be used together with reference standard meter.

Also can be operate by the keyboard on the faceplate

With LED indicator on the face plate after power on the unit

With voltage measurement facility and loop back control.

With measurement mode selection, namely 3P3W, 3P4W and 1P2W. When select 3P3W, automatically deactivate L2 phase current and when select 1P2W, automatically deselect L2 and L3 phases.

With overload, short circuit and thermal overload protection.

When accuracy of the unit changes, can calibrate it by given method by yourself.

With package avoiding damage and disturbance.

Single phase power supply, range 85-282V, 47 to 63Hz.

Working conditions: -10℃ to 50℃， 10%-95% R.humidity.
