VM-751B2 SHINKAWA Main Product Advantages

1.Supports a universal 100–240 VAC wide input voltage range, compatible with global industrial power grids without additional voltage transformers.

2.Enables redundant power operation when paralleled with the VM-751B1 primary power supply, preventing system shutdown caused by single power source failure.

3.Integrates built-in overvoltage, overcurrent and short-circuit protection, automatically cutting off output under abnormal conditions to protect rear-end monitoring modules from damage.

4.Features front-panel POWER and AC LED indicators for intuitive real-time status display and rapid power fault diagnosis without external testing tools.

5.Adopts full AC-DC electrical isolation design, effectively suppressing grid surge interference and ground loop noise to ensure stable signal collection of the whole monitoring system.

6.Adopts a compact 19-inch rack plug-in structure, saving cabinet space and offering full compatibility with all SHINKAWA VM-7 series modules for flexible system configuration.

7.Equipped with industrial-grade circuits and aluminum alloy housing, delivering excellent vibration resistance and stable performance in harsh power and petrochemical working environments.

8.Supports direct drop-in replacement of original modules with no need for wiring modification or parameter resetting, simplifying on-site maintenance.

9.Complies with CE safety standards and adapts to general industrial and Class I Division 2 hazardous area application scenarios.

10.Utilizes high-efficiency integrated power conversion circuitry to reduce overall system power consumption and lower long-term operational costs.

VM-751B2 SHINKAWA Wiring Method

The module integrates rear golden edge bus connector for power output connection with VM-7 series rack backplane, and front panel AC input terminal with locking screw structure for mains power access. The AC input terminal supports solid copper wires from 0.75mm² to 2.0mm², with independent live wire, neutral wire and PE protective grounding terminals separated by partition to avoid short circuit risks. All wiring terminals adopt screw locking design without crimp terminals required; the pluggable rack structure allows front-side module disassembly without cutting rear wiring during maintenance. Separate shielding ground wiring is reserved to restrain electromagnetic interference generated by AC power circuit.
