Bolec CP1224LH – The Trusted Workhorse for 24V Charging Systems
When reliability matters, Australian electricians turn to the CP1224LH – a charger built for real-world performance, long life, and full repairability.
In today’s infrastructure-driven world, dependable DC power is the backbone of emergency systems, control panels, industrial plants, and fire safety networks. Power failure isn’t just inconvenient — it can be dangerous. That’s why having a battery charger that you can trust over the long haul is critical, and it’s why electricians, engineers, and specifiers across Australia have relied on the Bolec CP1224LH since the 1990s.
Designed and manufactured in Heidelberg West, Melbourne, the CP1224LH has become a staple in installations where uptime and durability are non-negotiable. With a reputation built over decades, this unit combines robust hardware, serviceable design, and performance tuned for mission-critical environments.
Locally Built for Australia’s Toughest Environments
Unlike many imported chargers that are sealed and disposable, the CP1224LH is purpose-built in Australia. We understand local conditions — from dry, dusty engine rooms in regional fire stations to high-humidity pump rooms and clean technical environments in hospitals and control centres. Australian electricians don’t just want a charger that works — they want one they can rely on for years without worry. That’s why Bolec designs every component with resilience and longevity in mind.
Each CP1224LH unit is assembled and tested in Melbourne by trained technicians with deep product knowledge. Our chargers are not batch-assembled overseas and relabelled — they are manufactured with pride and traceability at every step. With ongoing support, parts availability, and local service expertise, you’re never alone when something needs attention.
What Makes the CP1224LH Unique?
- Repairable design – not sealed or throwaway; internal access is simple for technicians
- High reliability – fewer components, robust construction, proven to last over 15+ years in real-world use
- Critical-use validation – installed in hospitals, fire systems, and public transport across Australia
- Reverse polarity & short circuit protection – essential for peace of mind
- Manual override fan – rare for this class; ensures thermal stability in harsh sites
- Low RF interference – safe for use near communications, telemetry, and medical equipment
Built with Long-Term Thinking
We design for a 10+ year life — and back that up with spare parts availability, circuit-level repair support, and local service engineers who know the product inside out. Where other chargers are sealed shut, ours are made to be opened, cleaned, inspected, and repaired. Many of our CP1224LH units installed in the 2000s are still operating reliably today — a testament to both their quality and the foresight of electricians who chose Bolec in the first place.
