Dimensions:- 208 mm x 155mm x 115mm (W x H x D)
Input voltage:- 230V ±5%
Output voltage:- 0-15V AC at full load
Slightly smoothed DC (by 2200µF output capacitor) gives
practical r.m.s values of 0 -15V at no load.
"The 605-055 are unregulated power supplies so, it is normal for the output voltage to be higher than selected when they are under low or no load. It will approach the selected value as the load approaches full rated current. The digital display on the front of the unit only indicates the transformer tapping selected; it is not a voltmeter connected to the output.The discrepancy between the selected and actual voltages will be larger for the DC output under low loads as this output is a rectified version of the AC output. At very low currents the rectifier and smoothing capacitor will be picking the tops off the AC waveform so the DC voltage will be close to √2 times the RMS AC voltage."
