The PVAxx-27Bxx series features an ultra-wide and ultra-high input voltage range of 85-900 VAC, meeting the voltage fluctuation requirements of 127/220/380/660 VAC commonly found in coal mining. The PVA40-27Bxx (138x82x32mm) and PVA70-27Bxx (155x95x41mm) series are smaller than traditional industrial frequency transformer solutions with AC/DC power supplies. Furthermore, they have only one input port and do not require cable changes, eliminating the risk of incorrect connections and reducing application costs for the customer. Additionally
, the PVAxx-27Bxx series boasts an isolation voltage of 4000 VAC, an industrial operating temperature range of -40°C to +70°C, and an EMS EFT/Surge protection of ±4KV. Output short-circuit, overcurrent, and overvoltage protections are included.
Applications:
Widely used in coal mine control system applications and the security industry.
Features:
● Specially designed for electrical equipment in coal mining.
● Ultra-wide input voltage range of 85–900VAC.
● Industrial-grade operating temperature: -25°C to +70°C.
● High I/O insulation test voltage of 4000VAC.
● EMS EFT/Surge: ±4KV.
● High reliability, high efficiency, and long service life.
● Protection against short circuits, overcurrents, and overvoltages at the outputs.
