BLASI – Switching power supply
The BLASI Switching power supply converts 230VAC mains to stable 24VDC for control circuits, sensors, and auxiliary systems in revolving door canopies. Compact DIN-rail unit powers EPROM controllers, Merkur detectors, light curtains, PTC heaters, and thermostats in K21/K41 installations. Short-circuit/overload protection with auto-recovery ensures 24/7 uptime while universal input suits Dubai electrical standards. IP20 design mounts beside motor drives via WAGO terminals. Essential power source maintaining safety monitoring, climate control, and diagnostics for continuous luxury hotel/mall entrance operation.
Product Details
The BLASI Switching power supply provides reliable 24VDC distribution for automatic revolving door electronics. Universal 100-240VAC input handles voltage fluctuations while high-efficiency SMPS minimizes heat in confined canopy compartments. Capacity supports simultaneous operation of main EPROM controllers, Merkur 2ES motion sensors, Micro MF SY-900-8 light curtains, EAGLE ONE safety beams, PTC HP05 heating elements, thermostats, and remote diagnostics across K21/K41 systems.
Engineers mount DIN-rail enclosures near motor controllers, distributing power through color-coded WAGO terminals to sensor circuits and safety relays. Integrated protections prevent cascade failures during lightning surges or motor faults while low ripple ensures clean operation preventing false alarms from motion detectors. –20°C to +70°C range covers Dubai extremes while parallel operation enables redundancy.
In prestige installations, stable 24VDC powers emergency stop circuits, obstacle monitoring, night closure controls, and service interfaces essential for Civil Defence certification. Metal enclosure dissipates heat effectively while halogen-free materials comply with fire codes. Superior to linear transformers through 88% efficiency reducing cooling needs.
