Analog Volt and kW Meter BLOW 51-350# — large 500 V panel instrument

BLOW 51-350# — large 500 V panel instrument is an analog volt and kW meter designed for direct visual monitoring of voltage and power on control and distribution panels. The instrument features a large-format dial and analog needle readout that present instantaneous voltage (up to 500 V) and power (kW) values. Its construction is intended for fixed panel mounting in industrial environments, workshops and service cabinets where a simple, reliable real-time indication is needed.

Advantages

The meter provides a clear, easy-to-read analog display that allows quick visual assessment of electrical parameters without digital distractions. A large scale and needle movement make changes in voltage and power immediately noticeable. The robust panel housing and standard mounting format ensure stable installation in electrical panels and cabinets. The device operates without complex software or configuration, making it suitable for straightforward monitoring tasks.

Suitable for

• Industrial control panels and switchboards
• Power distribution boards and substations
• Workshops and maintenance stations
• Generator sets and local power monitoring

Key specifications

• Measurement functions: AC voltage and power (kW) indication
• Maximum voltage range: up to 500 V
• Display type: analog needle with large-format dial
• Mounting: panel-mounted instrument for fixed installation
• Operating principle: direct analog indication for real-time reading

How to use

Install the instrument in a compatible panel cutout and secure it according to panel mounting guidelines. Connect the voltage input and any required power-sensing inputs following the electrical schematic and safety rules appropriate for the installation. After correct wiring and power-up, the analog needle will indicate present voltage and corresponding power scale values. Periodically check mounting tightness and wiring connections as part of routine maintenance to ensure reliable readings.

Usage recommendations

Place the meter where the dial is clearly visible from the operator position and avoid locations exposed to direct moisture or excessive vibration. Use appropriate overcurrent protection and isolation when wiring. For installations requiring high accuracy or logging, consider combining the analog meter with additional digital instrumentation or data-acquisition devices.
