PULS UK has announced the PAS395 power supply developed to charge the latest super-capacitors used to power wind turbine pitch control systems. Super-capacitors (electrical double-layer capacitors) are rapidly replacing the lead acid batteries previously used to drive the powerful motors controlling the giant turbine blades. The supply delivers a high-charging current whereby a two-Farad capacitor will be fully charged in five minutes. The unit's high efficiency means that very little heat is generated. Once charging is complete the charger automatically switches to energy saving mode to reduce power losses. It operates in ambient temperatures of between -40 to +65°C and at an altitude of up to 6000m, making it suitable for all climatic conditions and locations. Remote monitoring and control are standard features. The supply is lightweight, it weighs just 2.3kg and measures 310x154x80mm.
