SHINKAWA VM-5Z4 Power Supply Module

The SHINKAWA VM-5Z4 is a dedicated power supply module designed for the VM-5 series machinery protection system. Installed in VM-5H3 or VM-5W1 rack chassis, this module provides regulated DC power to all monitoring modules, ensuring stable operation of the entire monitoring system in critical rotating machinery applications.

Technical Specifications

The power supply module supports multiple input voltage options, accommodating various facility power configurations. Output power capacity is sufficient to support a fully populated 8-slot rack with all monitoring modules operating at full load. The module includes overcurrent, overvoltage, and short-circuit protection to safeguard connected modules from electrical faults.

• Input Voltage Options: 100-240 V AC or 24 V DC (selectable)

• Input Frequency: 50/60 Hz (AC input)

• Output Voltages: Regulated DC for VM-5 series modules

• Output Capacity: Sufficient for full 8-slot rack population

• Protection Features: Overcurrent, overvoltage, short-circuit protection

• Status Indicators: Power good LED, fault LED

• Form Factor: Occupies one slot in VM-5 series chassis

• Operating Temperature: 0°C to 65°C

Redundant Configuration

For high-availability applications, two VM-5Z4 power supplies can be installed in a VM-5 series chassis in a redundant configuration. The redundant architecture ensures continuous operation of monitoring functions even if one power supply fails, with automatic load sharing and failover. A status output provides notification of power supply faults for remote monitoring.

Installation and Maintenance

The VM-5Z4 installs in a dedicated slot within the VM-5H3 or VM-5W1 chassis, typically at the left side of the rack. The module features front-panel access for power connections and status indication, with the power supply unit designed for hot-swap replacement in redundant configurations. This allows maintenance without system shutdown in critical applications.
