DD-Series
The DD-40VHz is a compact, dual 4.0 digit red LED display of AC volts and frequency. The combination of ACV and Hz makes the DD-40VHz ideal for generator set and other stand-by power applications. Both the voltmeter and the frequency meter will display to 0.1 resolution.
Each DD-40VHz has a two-position display intensity se lec tion.
With this display dimmer feature, the DD-40VHz can easily be seen in direct sunlight. Then the low intensity setting can be selected for night operation.
The DD-40VHz is housed in a short-depth 2.2" (111 mm) deep, 96X48 mm 1/16 DIN horizontal case. This compact case style allows for maximum visibility while demanding a very small panel space. The DD-40VHz uses a high-efficiency AC/DC switching power supply that allows operation from any AC voltage (85 to 265 VAC) or DC voltage (90 to 380 VDC).
The DD-Series have a matching DIN case style that is complementary to the Lynx, Leopard and Tiger family of meters. DD-Meters are the OEMs choice for economical switchboard and process indication. For economy, each model is dedicated to a specific application and designed for quick and easy installation.
