Technical Specifications Rated primary input voltage, rated secondary output voltage, specified power capacity. Dry‑type insulation construction. Operating ambient temperature 0 ℃ to +40 ℃, storage temperature ‑25 ℃ to +70 ℃, relative humidity 5%‑95% non‑condensing. Complies with industrial low‑voltage component safety standards. Terminal block wiring configuration.
Functional Features Converts incoming mains voltage to isolated control circuit voltage. Provides galvanic isolation between primary side and secondary side. Delivers stable auxiliary power for cabinet automation components. Restrains partial surge interference transfer between power network and control loop. Designed for continuous 24‑hour operation. Built‑in thermal withstand capability for normal industrial cabinet environment.
Application Scenarios Auxiliary power spare component for GE control cabinets, motor control centers and industrial automation systems. Widely deployed in power plant auxiliary equipment, water treatment, manufacturing production line control cabinets.
Performance Parameters Nominal power capacity, primary‑to‑secondary isolation dielectric strength, low voltage regulation deviation under rated load, low no‑load loss.
Material Composition Silicon‑steel laminated magnetic core. Enameled copper winding coils. Flame‑retardant insulated bobbin. Metal protective enclosure. Screw‑type wiring terminals and metal mounting brackets. Insulating paper and resin impregnation material.
Structural Characteristics Compact enclosed rectangular housing. Primary wiring terminals and secondary wiring terminals are separated on different sides of housing. Bottom pre‑drilled mounting holes for cabinet back‑plate installation. Magnetic core and windings are fully enclosed to prevent dust accumulation. Clear physical separation between high‑voltage primary terminals and low‑voltage secondary terminals.
Working Principle Magnetic flux couples to secondary winding and induces target secondary AC voltage.
Installation Requirements Tighten terminal screws to specified torque value. Maintain sufficient surrounding clearance for heat dissipation. Verify input and output voltage value after power‑on.
Usage Notes Operating load cannot exceed transformer rated capacity. Do not operate without proper enclosure protection. Ensure good ventilation environment to avoid overheating. Strictly prevent mis‑wiring of primary and secondary terminals.
