Product Q&A

Q:What defines a "Hybrid-Digital" system in this rectifier cabinet?

It means the power rectification is handled by robust analog SCR bridges, while the monitoring and control logic is managed by a high-precision digital PCB.

Q:Can this unit charge both Lead-Acid and Nickel-Cadmium batteries?

Can this unit charge both Lead-Acid and Nickel-Cadmium batteries?

Q:Does the cabinet protect against earth leakage?

Yes, it includes specialized Positive and Negative Earth Fault indicating lamps and alarms for early hazard detection.

Q:How does the "SID" option benefit the connected load?

The Silicon Dropping Diode automatically regulates output voltage during boost charging, preventing sensitive loads from being exposed to excessive voltage.

Q:Is the 50A rating the maximum capacity?

The standard model supports up to 50A, but we can customize the charger rating and cabinet size to meet higher power requirements.
