This equipment is the one having produced it for the examination of Over Currency Relay of AC, and 0 〜 100rms can be output as an exchange over current.
The output current value can be set in detail with a large-scale dial (ten rotations)(with built-in the liquid crystal ammeter).
The power supply can be driven with the outlet of the AC100 V, and the output is insulated with the transformer.
The output wave form is generated with an internal direct digital synthesizer, and the frequency accuracy is within +/-0.02%(Even 45 〜 65Hz can be adjusted at intervals of 1Hz).
The output current step change function (The increase and decrease can be selected) is provided, and the trigger signal that synchronizes with it is output.
The over voltage output protection and the over current output protection function are possessed as internal circuit protection.
