The power supply is adjustable, and it can be used as a fixed power supply for product testing on the production line. The power supply has the perfect protection function and the remote system function, is simple and convenient for the user.The ACME series DC power supply has fast dynamic response, low output ripple and strong over current capacity. It has the advantages of light weight, small volume, low noise, high efficiency, simple operation and so on. It can be applied to manufacturing, testing and maintenance of military electronic equipments, such as aircraft, airborne equipment, radar, navigation, etc., as well as industrial and mining enterprises, universities and laboratories, research institutes, etc.Performance characteristics1. stabilized voltage and current. Digital keyboard operation, voltage, current from zero to rated value adjustable, output voltage and current value set in advance. This product can work in the fixed voltage (CV) mode or the fixed current (CC) mode, the working mode switches automatically, and indicates the condition of the working mode via the LED. When CV-LED lights up, the power works on a fixed voltage mode, and when the CC-LED is on, the power is working in a fixed current mode.2.High precision, low ripple. The DC power supply is controlled by peak current, and has good load and power regulation rate, and the output voltage and current precision are high. The output is equipped with a multilevel filter, and the output ripple is low.3.High efficiency. The soft switching technology with international advanced level makes the power supply high efficiency, low noise and high reliability; the efficiency of the whole machine is higher than 95%.4.The protection function is complete. There is an overload protection circuit inside the power supply to ensure the normal operation of the power supply equipment and the safety of the load.5.Output display. The voltage and current are displayed with high precision LED digital meter.6.Digital control. All digital control, voltage and current can be realized through digital programming; all the calibration is digital calibration, stable and reliable.7.Remote control function. The power supply is equipped with RS485 interface and can communicate with the computer through the MODBUS protocol. It supports multi machine communication and reliable verification. Each 485 interface supports up to 255 power supplies and realizes monitoring at the same time. The computer can monitor all the parameters and states of the power supply remotely. The upper computer can realize remote parameter setting and control function according to authorization.Technical parameters:Capacity Control modePWM ZVZCS soft switching inverter technologyControl technology16 bit MCU+CPLDInputInput voltage rangeSingle phase 220V±15%/Three phase 380V±15%Frequency47-63HZOutputexternal characteristicCV & CCRating output voltageRating VOutput voltage range0~ Rating V adjustableRating output currentRating AOutput current range0~100% Rating output currentSource voltage stability< 0.5% @FSLoad stability< 1% @FSripple voltage(r.m.s)< 0.5% @FSTransient response time90% @ 100% loadDisplaydigital voltmeter4 bit LED display (0.1V) specification:±0.5%rdg+2digitdigital ammeter4 bit LED display (1A) specification:±0.5%rdg+2digitWorking conditionsstorage temperature-20ºC~+50ºCworking temperature-10ºC~+40ºCrelative humidity≤95%(no condensation)levels of protectionIP20atmospheric pressure80~106KPc(altitude below 2000m)noise< 65 dB at 1 meterProtectionThe input phase lack protectionThree phase input short phase protection and alarmInput overvoltage protectionStop working and alarm when the voltage of input is output of the rangeInput under voltage protectionStop working and alarm when the voltage of input is output of the rangeOutput over voltage protectionAutomatic protection and alarm when the output voltage is higher than the set valueOutput overcurrent protectionThe output current exceeds the set value.automatic current limiting after delay start.short-circuit protection The output end can be short circuited for a long time, and there is a sound and light alarm when short circuit.When the short circuit is removed, the power is automatically restored to normal workoverheat protection>85ºC protect and a
