Yokogawa 250340LSPZ7 UL Panel Meter & Powerstat 10C Variable Transformer

Description:

The Yokogawa 250340LSPZ7 UL panel meter with Powerstat 10C variable transformer is used in electrical measurement and variable voltage control systems. Commonly installed in test benches, control panels, and laboratory setups for monitoring and adjusting electrical parameters. Maintenance technicians, engineers, and system integrators use this combination for voltage control, system testing, and instrumentation replacement or upgrades.

Applications:

The Yokogawa 250340LSPZ7 panel meter paired with a Powerstat 10C variable transformer is used in industrial and laboratory environments to monitor electrical values while adjusting voltage output. The panel meter provides real-time analog indication (typically current or voltage), while the Powerstat transformer allows precise manual control of AC voltage levels. This setup is widely applied in equipment testing, calibration systems, power supply regulation, and educational or R&D environments where controlled variable voltage and accurate measurement are required. Panel meters in this series are known for their large, easy-to-read analog displays and are commonly used in control panels and instrumentation systems.
