SHINKAWA VM-5Z1/IS0 Power Supply

Name: Shinkawa VM-5Z1 Power Supply Unit – Datasheet & Price Quote
Brand: Shinkawa

Description

Overview

The Shinkawa VM-5Z1 Power Supply Unit provides stable DC power to the monitor and relay modules within a VM-5 series instrument rack, forming the backbone of the machinery protection system. It accepts a wide range of AC or DC inputs and generates the multiple voltage rails required by VM-5 modules.

Designed for continuous operation in industrial environments, the VM-5Z1 delivers the +5V, +17V, +24V, -15V, and -30V rails needed by VM-5 monitoring electronics, with LED indication of each rail’s status on the front panel.

Engineering & Design

The power supply accepts 85-264 VAC or 88-144 VDC input, covering the electrical supplies found in most industrial plants, and provides an OK alarm contact rated 250VAC 5A / 30VDC 5A for connection to annunciation systems. The relay mode is configurable as normally energized, allowing the alarm philosophy to be matched to the installation.

With a maximum power consumption of 265 VA, the VM-5Z1 is sized to power a fully populated VM-5 rack, and the plastic-sealed construction protects the unit in the rack environment. It operates from 0 to 65 C with storage capability from -30 to +85 C.

About brand

Turbine and compressor trains in many Asian-built power and process plants are protected by Shinkawa vibration monitoring. Shinkawa Electric Co., Ltd. of Tokyo makes eddy current displacement transducers, vibration sensors and rack-based monitors for rotating machinery. Seven Star LLC lists Shinkawa VM-5 and VM-700 series monitor modules, sensors and converters, and sources them by full model code for machinery protection systems in Oman.

Shinkawa's current catalog also shows the FK transducer series and the VM-7 monitor. This matters when an older part has to be matched with a present-day equivalent.

How a Shinkawa protection chain works

An eddy current probe sits a set distance from the shaft. Its driver (converter) turns the gap into a voltage, and the monitor turns that voltage into vibration, thrust position or speed values with alert and danger set points. The probe, extension cable and driver are calibrated together for one total system length and one target material, usually AISI 4140 shaft steel. Changing one part without matching the other two shifts the calibration. The monitor relays feed the turbine or compressor trip logic, and buffered outputs go to analysis systems. Many protection systems of this kind are specified to API 670.

Where Shinkawa vibration monitoring is used

Shinkawa systems measure shaft vibration, axial (thrust) position, speed, phase reference and bearing temperature on steam turbines, gas turbines, generators, compressors, pumps and fans. In the GCC they are found mainly in power stations, desalination plants, refineries and petrochemical units with Japanese or Korean machinery packages.

Ordering Shinkawa parts: what we need

Shinkawa model codes are long and every field counts. A monitor code such as VM-5K-411512-000-000-111-0/IS0/EX5 defines the input type, range, options and suffix codes, so copy the complete string from the module label, including everything after the slashes. For sensors, send the VL or FK model code, probe tip diameter, cable length and the matching driver or converter model, since the probe, extension cable and driver work as a calibrated set. A serial number and a photo of the label help us confirm the item in the manufacturer's documentation. Where a model is no longer produced, we propose the successor the manufacturer names.
