Analog Multimeter BLOW 51-501 — ammeter and kW indicator, mini size, 1 A range with shunt

The BLOW 51-501 analog multimeter combines an ammeter function with a kW indicator in a compact mini housing designed for panel mounting. Specified for a 1 A measurement range and supplied with a dedicated shunt, the instrument provides a simple analogue readout for monitoring current and estimating power in equipment panels, control cabinets and small electrical installations. Its small footprint allows installation where space is limited while maintaining clear needle indication and basic power scaling.

Advantages

The instrument offers a straightforward analogue display that requires no digital configuration and delivers immediate, real-time indication of current and power. The integrated shunt enables accurate measurement within the 1 A range while the mini housing simplifies mounting in crowded panels. Mechanical construction and scale calibration are optimized for clear needle response under normal operating conditions.

Suitable for

• Monitoring current in control cabinets and distribution panels
• Estimating power (kW) for small motors and equipment within the specified range
• Retrofit installations where a compact analogue indicator is preferred
• Simple local indication during maintenance and troubleshooting

Key specifications

• Measurement type: analogue ammeter with power (kW) indication
• Nominal current range: 1 A (with external shunt provided)
• Display: needle (analogue) with printed scale calibrated for current and power
• Housing: mini panel-mount form factor suitable for limited-space installations
• Application environment: indoor electrical panels and control cabinets

How to use

Mount the meter in a suitable panel cut-out and connect the supplied shunt in series with the load according to standard wiring practice. Connect the meter input across the shunt output terminals to read current; the instrument’s scale provides kW indication based on the calibrated relationship for the nominal system voltage. Ensure wiring is secure and observe polarity where applicable. No software configuration is required; the needle provides continuous real-time indication once power is applied.

Usage recommendations

Install the device in a dry, vibration-minimized location inside the control cabinet, away from heat sources and strong magnetic fields. Verify the meter’s range and shunt rating match the expected operating current; avoid exceeding the nominal 1 A range to prevent measurement error or damage. Periodically inspect connections for corrosion and secure mounting to maintain reliable analogue readings.
