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.

The Texmate DD-40VHz uses a standard PC board edge connector with two rows of 15 pins, spaced on 0.156" centers, for signal and power connection. The DD-40VHz is designed for simple con nec tion to the signal source. There is only one signal input for the AC voltage being monitored. The frequency is automatically sensed and displayed on the right-hand side of the DD-40VHz.

The DD-40VHz is supplied from the factory with an in ter nally isolated auto-sensing AC/DC switching power supply. The pow er supply will operate from an AC voltage within a range of
85 to 265 VAC and 90 to 380 VDC. If the power source to the DD-40VHz changes from AC to DC, the DD-40VHz will continue to operate. Although specified to operate from 85 to 265 VAC, the DD-40VHz can still function with an AC supply as low as 40 VAC. Texmate recommends that the AC power source be within the specified range of 85 to 265 VAC.
The AC input signal is rectified and averaged before being sampled by a single-slope A/D converter. From the A/D con vert er, the AC input signal and the digital rep re sen ta tion of the input voltage are fed into a microprocessor to cal cu late the frequency.
Both the AC input voltage and the frequency are displayed on two separate four-digit, sevensegment LED dis plays.
With an external switch, the meter display can be set to two levels of brightness. The microprocessor de tects the dis play selection setting of the switch and, in turn, applies this setting to the display.

The DD-40VHz is calibrated at the factory with a precision AC voltage source. A calibrator of 0.05% accuracy is re quired to completely check the operation of the DD-40VHz meter.
1. Carefully snap off and remove the front bezel, clear protec-tive cover, and filter. The span adjust pot will now be visible.
2. Make sure there is a proper AC or DC power source avail-
able that is within the specified pa ram e ters.
3. Connect the power source to Pins 1 and 3 (Pins A and C).
4. Connect the cal i bra tor to the input signal pins 6 and 8 (Pins F and J) and apply an AC voltage between 90 and 350 VAC.
5. Adjust the span potentiometer at the front of the meter until the displayed AC voltage reading agrees with the calibrator input signal. Frequency calibration is not required.
6. The DD-40VHz is now calibrated and ready for use.
The DD-40VHz is supplied from the factory with an internally isolated auto-sensing AC/DC switching power supply. This power supply will operate from an AC voltage anywhere within a range of 85 to 265 VAC or 90 to 370 VDC.
If the meter's power source changes from AC to DC, the DD-40VHz will continue to operate. The DD-40VHz, although specified to operate from 85 to
265 VAC, can still function with an AC supply as low as
40 VAC. It is recommended that the AC power source be within the specified range of 85 to 265 VAC.
They provide the greatest convenience and ease of use
Texmates exclusive optional Push-On Connectors combine an edge card connector and a 10 position screw terminal block. Push-On Connectors are ordered preconfigured for each specific power supply voltage and each optional power supply available for the DD-Series.
A standard 30-pin edge card connector can be used to connect the DD-40VHz. As an alternative, however Tex mate has de signed an ex treme ly easy-to-use connector called the PushOnTM connector. This exclusive connec tor de sign combines an edge card con nec tor and screw terminal blocks into one piece.
To order, use part num ber DD-PUS H /DD.
A standard 30 pin edge connector (two rows of 15 pins on 0.156" centers) may also be used to connect the DD-40VHZ.
