Preen BPS Series

A ship docked at berth needs shore power that can survive the marine environment it's deployed in — salt air, high humidity, and heat — while still delivering clean, stable power to genuinely abusive electrical loads. Preen's BPS series is purpose-built for exactly this application: a high-performance shore power supply developed specifically for shipbuilding facilities, berths, and vessels, engineered to operate reliably under conditions that would degrade standard indoor power equipment.

Output power scales up to 2000kVA at 440V (L-L), with frequency handled two ways depending on model: BPS-F provides continuously adjustable 47-63Hz output for facilities needing a fixed conversion range, while BPS-V offers wide-range 45-65Hz input, suited to broader frequency-variable requirements. IP54 protection is rated as standard, housed in a customised outdoor-rated container rather than requiring a separate weatherproof enclosure to be built around a standard indoor unit — a meaningful difference for berth installations where the equipment is genuinely exposed to marine weather conditions.

Overload capability (110% for 1 hour, 150% for 1 minute) covers the load variability typical of vessel power draw, and efficiency reaches up to 92% on BPS-F models or 95% on BPS-V models. A patented power module design keeps the unit compact for its power rating while supporting easier maintenance access, and comprehensive protection — over voltage, over current, overload, input under voltage, and over temperature, each with corresponding error codes — supports fast fault diagnosis in an operational berth environment where downtime has direct cost implications.
