Conversion switch meter

This AC voltmeter with integrated selector switch (also referred to as a conversion switch meter) is designed for flexible, selective voltage measurement across three-phase electrical systems. Its switchable measurement positions eliminate the need for multiple standalone meters, enabling efficient monitoring of line-to-line and line-to-neutral voltage values with a single device.

Expanded Technical Specification: Voltmeter with Selector Switch (Conversion Switch Meter)

Product Overview

Measuring Range: Direct AC Voltage Measurement
The voltmeter supports direct AC voltage measurement without the need for external voltage transformers (VTs/VTs), covering a broad range of industrial and commercial system voltages:Direct Measurement Range: 0 ~ 600 V AC

Selector Switch Position Configurations
The meter is available in two selector switch configurations to match different three-phase system topologies, with customizable options for enhanced operational flexibility:

1.1 3-Position Selector Switch (For 3-Phase 3-Wire (3P3W) Systems)
Target Application: Optimized for 3P3W electrical systems where no neutral conductor is present (e.g., industrial motor drives, utility transmission lines).Measurement Positions:
L1-L2: Line-to-line voltage between Phase 1 and Phase 2
L1-L3: Line-to-line voltage between Phase 1 and Phase 3
L2-L3: Line-to-line voltage between Phase 2 and Phase 3
Customization Option: An additional OFF position can be integrated into the selector switch upon customer request, allowing the meter to be electrically disconnected from the system when not in use.

1.2 6-Position Selector Switch (For 3-Phase 4-Wire (3P4W) Systems)
Target Application: Suited for 3P4W electrical systems with a neutral conductor (e.g., commercial buildings, data centers, unbalanced load environments).Measurement Positions:
L1-L2: Line-to-line voltage between Phase 1 and Phase 2
L1-L3: Line-to-line voltage between Phase 1 and Phase 3
L2-L3: Line-to-line voltage between Phase 2 and Phase 3
L1-N: Line-to-neutral voltage between Phase 1 and Neutral
L2-N: Line-to-neutral voltage between Phase 2 and Neutral
L3-N: Line-to-neutral voltage between Phase 3 and Neutral
Customization Option: An additional OFF position is available as a factory option, providing a dedicated isolation state for maintenance or system shutdowns.
