I、Technical index and properties of the DC Voltage stabilized power supply
(DC Power Supplies)
   LW series of stabilized voltage and current power supply is researched and made with the international advanced technology of suspension and superposition. The circuit has functions of stepping down, rectifying, and filtering via transformer; adjustment with transistor of high power; and reference sampling and amplifying. The double circuit power supply can either output independently or be used in serial or parallel. In serial connection, the sub output voltage tracks the main one, while in parallel, the max. output current can be the sum of the output current of the two independent circuits.
Technical index:
1.Input voltage: AC220V±10% single phase or AC380V±10% three phases,50Hz±1Hz
2.Output voltage and current
(1)See table below
(2)Efficiency of the power supply :CV≤5×10-3+5mV CC≤2×10-3+10mA
(3)Load effect : CV≤5×10-3+5mV CC≤5×10-2+10mA
(4)Periphery and random shift: VP-P≤30mV
3.Index: voltage and current meters, one each, in an accuracy of grade 2.5 or three and half digital voltage and current meters, one each. The accuracy of the voltmeter is ±1%+2 digits, while that of the ammeter, ±2%+2 digits.
4.Operation environment: 0--40℃,relative humidity﹤90%。
