Reliable tripping supply for your switchgear
When the mains fail, your protection system runs on the battery. ChargePro keeps that battery healthy — automatic float and boost charging, full alarm monitoring, and built to run 24/7 in substation conditions.
Protection relays and breaker trip coils don't run on the mains — they run on a battery, kept charged by a charger. If the charger fails silently, your relays may not trip when a fault hits, exactly when you need them most.
ChargePro monitors itself and the battery continuously, raising alarms for earth faults, low volts, and charger failure — so a weak DC system never goes unnoticed.
A flat battery means breakers can't trip on a fault — the single most dangerous failure in a substation.
Charger faults give no outward sign until the battery is already drained. Alarms catch it early.
A healthy DC tripping supply is part of what your LEW checks at every inspection.
Filtered output protects sensitive numerical relays from ripple and voltage swings.
Manual/auto toggle between boost, float, and auto charging — holds the battery healthy day-to-day, recovers it fast after a discharge.
Heavy-duty analog voltmeter and ammeter on the front panel show real-time charger status and load at a glance.
Common alarm contacts for high/low volt, charger fail, and earth fault — smart dry contact loops report straight to your SCADA network.
All outputs fully isolated and individually protected by miniature circuit breakers — standard 2× AC and 1× DC outlets.
Dry cell, valve regulated lead acid (VRLA) blocks — no topping up, ≤3% self-discharge per month.
Output voltage, current limits, and battery amp-hours tailored to your switchgear — all within the same standard-footprint enclosure.
Standard configuration — voltage, current, and battery capacity are customizable within the same enclosure. Tell us your requirement →
One team, one point of responsibility — the same engineers who work on your switchgear handle the supply, installation, and commissioning of your DC system.
We size the charger and battery bank to your DC load and autonomy requirement, and deliver a unit built for your site.
Installation, cabling, and full commissioning tests — load test, alarm checks, and changeover verification before handover.
Every unit is covered by a 1-year warranty from commissioning — if anything fails, we make it right.
Tell us your DC system voltage, battery bank, and site conditions — we'll size the right charger and quote within 24 hours.
