The Technical Specifications of DC-UPS power supply KDC400-12
Guangzhou KAIHUI Electronics Co.,Ltd is the professional manufacturer of the switching power supply for more than 14 years. There are AC DC switching power supply,DC DC power supply,DC UPS power supply.This time let me introduce our hot selling model KDC400-12 to you.It is one of the DC-UPS power supply.
GENERAL SCOPE :
This specification defines the performance characteristics of a 13.8V, 25A equipment supply cum battery charger operating on Single phase AC supply;INPUT PHASE : Single phase, 2 wire and ground;
INPUT FREQUENCY:
50Hz~60Hz;INPUT VOLTAGE: AC 170V AC to 270V AC;EFFICIENCY: > 75% at 230V, Full load;
OUTPUTS:
The DC-UPS power supply has two output terminals i.e., Equipment and the Battery. Tlie Battery is directly floated across the Equipment internally. When battery is connected, the Equipment output terminal Will follow the battery voltage.
OUTPUT VOLTAGE AND CURRENT:
Equipment output-l3.80V at 25.0 Amps max.(without connect battery) Battery output 13.80V at 10.0 Amps max. (When the wireless set is not In transmit mode). Maximum output power (Equipment + Battery) is Limited to 400W max.
OUTPUT VOLTAGE ADJUSTMENT:
Output Voltage settable from 12.0V to 14.20V DC by adjusting the (V.adj.) potentiometer provided on the front panel.
BATTERY CHARGING:
Battery charging will take place with constant voltage, constant current. Maximum charging current of the battery will be limited to 10.0A + 20%. Maximum charging voltage to be 14.00V.
OUTPUT VOLTACE REGULATIONS :
With the Battery disconnected, output voltage will remain within +2% Of the set values. And when battery is connected the output will follow The battery voltage.
PROTECTIONS:
OUTPUT OVER VOLTAGE:: PSU trips on output over voltage condition (above 15V) and resume to normal operation on removal of fault condition and AC power. Re-cycling with 20sec interval between switch OFF and ON.

OUTPUT OVER VOLTAGE:: PSU trips on output over voltage condition (above 15V) and resume to normal operation on removal of fault condition and AC power. Re-cycling with 20sec interval between switch OFF and ON.
OUTPUT OVER LOAD AND SHORT CKT.:
Output folds back or Hick Up mode on over power or short circuit condition and resume to normal operation on removal of over power or Short circuit condition.
BATTERY REVERSE: On reverse polarity Red provided at Battery terminal Connecting side, Charge is protected against the reverse.
BATTERY DEEP DISCHARGE CUT-OFF:
During power off condition, the battery supply power to the equipment. When the battery voltage falls below 10.8V, a battery low LED Will turn ON and Buzzer alarm will be provided on continues mode to protect the battery from damage due to deep discharge the battery is Isolated from them equipment, when the battery voltage falls below 10.8V.After restoration of AC mains, to ensure the availability of required equipment current and Safety of the battery, the battery is initially charged with 1.0A current by an auxiliary charger, till the battery voltage reaches 1 1.40V, after which the battery is reconnected to the equipment and nonnal Charging (10.0A max.) takes place.
PRODUCT SAFETY: DI-ELECTRIC VOLTAGE WITHSTAND TEST: Tested at 1.5KV rms AC for one minute with a trip current of 5mA.
a) Between INPUT and CHASSIS.
b) Between INPUT and OUTPUT.
