Core functions and advantages (commonality+differentiation)

（1） Common core functions

High stability power supply guarantee

Adopting high-frequency switching power supply technology (switching frequency 20-50kHz), combined with precision feedback regulation circuit, the output voltage ripple is ≤ 50mV (far lower than the 100mV of ordinary power supply), even when the main grid voltage fluctuates (± 15%) or the load suddenly changes (20% -100%), it can still maintain stable output voltage, avoiding shutdown or misoperation of high-voltage frequency converters and PLC control circuits caused by power supply fluctuations.

Durable design for harsh environments

The shell is made of flame-retardant ABS material (UL94 V-0 grade), and the internal components are selected from industrial grade wide temperature models (-55 ° C to 125 ° C); Some models (such as GVC736BE101) have dust-proof mesh design, which can filter dust impurities in the air and extend the life of internal fans and components; The anti electromagnetic interference capability has been certified by IEC 61000-6-3 and can work normally in strong interference environments such as high-voltage frequency converters and high-power motors.

Full lifecycle security protection

Integrated overcurrent (threshold 120% -150% rated current), overvoltage (threshold 115% -130% rated voltage), short circuit (instantaneous cut-off, no damage), over temperature (triggered at 85 ° C-95 ° C) and anti reverse connection protection. Some models (5SHY3545L0016) additionally support surge suppression (input side 10kV surge protection) to avoid lightning strikes or power grid impact damage to the power supply; In the event of a malfunction, the LED indicator light (red/green dual color) provides a visual prompt for quick identification of the problem.

（2） Differentiation advantage

5SHY3545L0016/3BHB020720R0002: Featuring high-power output (20A/15A), suitable for multi module control circuit power supply of high-voltage frequency converters (such as ACS880), supporting parallel expansion (up to 3 units), with a total output current of up to 60A, meeting the needs of multi unit collaborative power supply for large frequency converters.

3BHE019719R0101: Single phase input design, suitable for small control room scenarios without three-phase power supply, optimized for S800 I/O system, compatible with wiring terminals and I/O modules, can achieve "power I/O" integrated installation, reducing wiring complexity.

GVC736BE101: Wide temperature tolerance (-25 ° C to 75 ° C)+DC 48V output, suitable for extreme temperature environments such as mines and outdoor substations, as well as control units in high-voltage equipment that require 48V power supply (such as high-voltage circuit breaker operating mechanisms).

Typical application scenarios

High voltage frequency converter matching

As an auxiliary power supply for high-voltage frequency converters such as ABB ACS880 and ACS600, it provides DC 24V power supply for the control board, IGBT drive circuit, and cooling fan of the frequency converter, ensuring uninterrupted parameter configuration during startup and status monitoring during operation. It is typically used in the main drive of rolling mills in the metallurgical industry and large fans in the chemical industry.

Control circuit of power electronic equipment

In power compensation equipment such as SVG (Static Var Generator) and APF (Active Power Filter), stable DC power is provided for the detection module (current/voltage sensor) and logic control unit of the equipment to ensure the normal operation of reactive power compensation and harmonic control functions in the power system. It is commonly used in new energy power stations and large factory distribution networks.

Power supply for large PLC and I/O systems

Provide centralized power supply for ABB S800, S900 series PLCs and distributed I/O modules (such as AI801, DI801), especially suitable for reactor control in chemical production lines and pressure monitoring systems in oil and gas pipelines, to avoid production process interruptions caused by power failures.

High voltage equipment operating mechanism

GVC736BE101 and other DC 48V models are designed to supply power to circuit breakers and isolating switch operating mechanisms in high-voltage switchgear. They support remote opening and closing control and are compatible with high-voltage power facilities such as substations and converter stations, ensuring the reliability and timeliness of operating mechanism actions.
