Red Lion Controls APLVD400 Industrial Panel Meter

The Red Lion Controls APLVD400 Apollo DC Voltmeter is a panel-mounted, solid-state voltmeter that displays DC voltage on a bright red LED readout for easy visibility in industrial panels. As part of Red Lion’s Apollo voltmeter family, it covers a DC measurement range of 1.999 to 300 V and is intended for panel installations where a dedicated DC voltage indication is required. The model is documented as obsolete and no longer manufactured, reflecting its status as legacy equipment. Some listings note a power/supply specification around 115 V (with references citing 115 VDC or 115 VAC input depending on documentation), while the device remains described primarily as a DC voltmeter with a red-panel LED display. This makes the APLVD400 suitable for monitoring DC power rails in control panels, process equipment, or instrumentation where a compact, panel-mount voltage readout is preferred over larger meters or external instrumentation.
