Analog Panel Frequency Meter 45-65 Hz 200-250 V Analogue Display Sifam Tinsley ZQ3L46023AW3000ST

What this product is for

This analogue panel frequency meter is used to monitor line frequency in AC electrical systems. It is commonly installed in switchboards, generator panels, and power distribution equipment where operators need a quick visual check of system frequency.

Use for

Use for 45-65 Hz AC systems with a 200-250 V input range. Common applications include generator control rooms, industrial panels, utility-related equipment, and OEM control assemblies.

Avoid for

Avoid for digital monitoring, remote communications, or applications requiring programmable alarms or data logging. Also avoid where the system voltage or frequency range does not match the meter scale.

Best for

Best for panel builders, maintenance electricians, and industrial users who want a simple analogue indication without auxiliary programming. It is a practical choice where fast visual confirmation matters more than multifunction metering.

Installed in

Typically installed in control panels and switchboards with an approximately 45 x 45 mm panel cutout and a meter depth of about 54 mm (2.1 in). Confirm panel opening and clearance before ordering, as exact dimensions can vary by series and configuration.

Why this product exists

This product provides direct local indication of system frequency so operators can confirm generator and supply stability at a glance. In generator and transfer applications, visible frequency indication helps identify abnormal operating conditions before they affect connected loads.

Compared with similar products

Compared with digital panel meters, this analogue frequency meter offers simple at-a-glance indication and straightforward panel integration. It does not provide communications or multifunction data, but it can be a good fit where a dedicated frequency display is preferred.
