Power supply -- Electronic Measurements Inc. TCR 1 Phase

Electronic Measurements Inc.
Model: TCR 1 Phase
Date: 1984
Category: Measurement instruments
Group: Power supply

Constant voltage mode; Variations in output current from 5 to 100% of maximum rating cause output voltage variations of less than 0.1% of the output voltage setting when output is 50 to 100% of the maximum rating. Below 50% output voltage, output variation will not exceed 0.05% of maximum output. Constant current Mode: Variations in- output voltage from 5 to 100% of maximum rating cause output current variations of less than 0.1% of the output voltage setting when output is 50 to 100% of the maximum rating. Below 50% output current, output variation will not exceed 0.05% of.maximum output Ripple: Measured with either positive or negative grounded, maximum output voltage and full current into a resistive load.'(See Rating Chart) At 50Hz AC input ripple is 30% above 60Hz ratings. Stability: The output voltage or current will remain within ± 0.05% for 8 hours after warm-up, with constant line, load and temperature. Transient Response: A 30% step increase inpower demanded by the load will cause a transient in the regulated output which will typically recover to within 2% of final value within 75ms.
