Microcomputer-controlled High-frequency Switching DC Power Supply Cabinet

Application fields:
Microcomputer-controlled High-frequency Switching DC Power Supply Cabinet used for the places where the DC voltage needed such as the thermal power station, hydropower station power substation, switchgear station, pump station, industry company etc for the power supply to the breaker or equipment operation, control system and lighting.
Main Functions:
(1) Adopts multiple high-frequency switch power supply charging modules connected in parallel, creating standby between them and high reliability.
(2) Adopts microcomputer smart control device for smart management of charging and discharging of charging modules and batteries, thus slashing maintenance workload.
(3)Adopts long-lived (10 years) maintenance-free lead-acid storage batteries, reducing battery maintenance workload almost to zero.
(4) Has "four remote" functions, realizing unattended operation.
(5) Adopts LCD display in Chinese characters with user-friendly interfaces, acousto-optic alarm, convenient operation.
(6) Supply power above 92%, power factor above 0.99, without pollution of grid harmonic wave.
(7) Equipped with sound measures against surge voltage and current.
(8) Adopts modular structure, allowing simple assembly and flexible configuration.
Standard functions:
(1) Fully automatic & manual charging & discharging management.
(2) Real-time display of module status, switch status, current, voltage and alarm status.
(3) Detection of three-phase input voltage and current as well as overvoltage, low-voltage, loss-of-phase and loss-of-power alarm.
(4) Detection of bus combining voltage and bus controlling voltage as well as bus combing & controlling overvoltage and low-voltage alarm.
(5) Battery voltage detection.
(6) Bus grounding alarm.
(7) History alarm event inquiry.
(8) Silicon chain manual voltage regulation & control.
(9) Realize "four remote” functions via RS32 or RS485 interface.
Optional functions:
1. Battery patrolling function, battery failure alarm.
2. Wire selection for branch circuit grounding.
3. Automatic voltage regulation control.
4. Detection of branch circuit feed wire status.
