D.C. Regulated Power Supply

Model 2971

D.C. Regulated Power Supply available in any fixed voltage from 5 volts to 30 volts. The regulator is temperature limited and time dependant current limited. This power supply incorporates a 'C' Core transformer which gives a low weight and small size compared to a 'E-l' Laminated type.

Specifications
Input Volts: 240 volt 50 Hz, 110 volt 50 Hz (available)
Load Regulation: Better than 0.5% no load to full load
Line Regulation: Better than 0.5% for 10% change in input volts
Total Noise: Less than 20mV R.M.S.
Protection: None. Input fuses should be rated 5 to 10 times full load input current
Current Limit: 14A approx. (7A for 5A model) Output is short circuit protected for models up to 24 volts
Peak output current: Minimum 20A for 1m second (10A for 5A model)
Ambient Range: 0° - 55° Celsius
Dimensions: See below

X = 0 for 110 Volts 50 Hz, X = 2 for 240 Volts 50 Hz, * 240V Input
 

Mains Input Variation: The power supply can be used at full output down to an input voltage of 210 Volts, however at low input voltages (below 240 volts) the output ripple will increase if output current exceeds nominal output X [mains input voltage-190]/50. The Model 2971-20 will give full output performance for input voltages from 200 to 245 Volts. Above 245 Volts the power supply can be used at full rated output however the maximum ambient temperature must be reduced by [mains input voltage-245] x 1 degrees celcius per volt. The input volts should not exceed 255V.

Non-standard Voltages: These power supplies are available for non-standard voltages.

Mounting: For maximum power mount with the longest dimension vertical. Do not obstruct airflow.
