solar battery charger / Ni-MH / handheld / for railway applications

Heavy-duty, Switch-mode, Portable Charger for 100Ah/12V NiMH Batteries

- Universal ac-input range
- PFC-input stage
- Cooling by natural convection - no fans required
- Housed in a splash-proof Pelican top loader case with a sturdy handle
- Suitable for applications where manual initiation of a charge cycle required
- Suitable for Railway & Industrial Environments

Battery voltage and temperature are monitored during the charge cycle. The battery temperature is monitored by an external sensor, which is connected to the charger via a 2-pole circular connector. The charging process is terminated when either the battery voltage reaches 13.5V or the battery temperature exceeds a predetermined temperature, at which point the charger disconnects from the battery via the contacts. For safety reasons, the circuit will not re-initiate automatically, even in case of input power re-cycling it must be initiated manually. Disconnect values can be made customer-specific.

A breaker and an internal crowbar diode on the charger output protect against reverse connection of the battery to the charger. Full electronic protection minimizes the possibility of failure due to abnormal operating conditions. The BCP 130-PEL complies with EN/UL60950-1 and equivalent industrial safety standards as well as the EN61000-3-2 directive for low input harmonic distortion. The unit is filtered to meet EN55022 Class A EMI standards with margins.

All printed circuits are conformal coated and heavily ruggedized for immunity to shock, vibration and moisture.

Custom options, versions with higher output power and versions for different battery chemistries and voltages, are also available.
