The following specifications describe the published operational characteristics of this series of power supplies. 250 Watts nominal output. AC Input: 250 watt model, 10 5™130V, 4 7-6 3Hz optional. Units are shipped with terminal block, line cord available on request. REGULATION: Voltage Mode: For line voltage variations and load current variations within the rating of the supply, the output voltage will not vary more than 0.1% of the maximum voltage rating. Current Mode: For line voltage variations and load voltage variations within the rating of the supply, the output current will not vary more than .25% of the maximum current rating. On those uni t s in which the percentage of voltage or current ripple exceeds the specified regulation, the regulation will appear to be degraded due to the effect of this ripple on the measurement. RIPPLE: Measured with either positive or negative grounded and 100% output voltage and cur rent into a resistive load. (See rating chart) (At 50Hz AC input is 30% above 60Hz rating) The output voltage or current will remain within 0.05% for 8 hours after warm-up, with constant external effects. TRANSIENT RESPONSE: Upon instant application of of the maximum rating of output voltage will recover its final value within 50ms line variations are corrected to 1% within 50ms of their' occurrence. TEMPERATURE COEFFICIENT: Output voltage T.C. is 0.02% per degree C of maximum rating, Output current T.C. is 0.03% per’ degree of maximum rating. OPERATING TEMPERATURE: 0-50 Degree C (0-40 Degree C for 50Hz input with no derating required. Derate current linearly to 50% of rating table {pg. ) at 71 Degree C ambient. STORAGE TEMPERATURE: -10 Degrees to +85 Degrees C GENERAL RESOLUTION: The voltage control is a ten turn potentiometer. The current control is a one turn cermet type potentiometer.
