Are you tired of searching various manufacturers to locate a clock that is compatible with your clock system? For those who desire a clock series that they can install on most any system with confidence, NATIONAL TIME has the answer. The NATIONAL TIME DU Series Digital Clock offers operation and features beyond those found throughout the industry. This microprocessor based secondary clock has the intelligence to adapt to the system on which it is installed. Not only does the DU series do everything the other National series digital clocks can, it can do so much more. Whether it is a 3-wire synchronous system with 58th minute correction or hourly correction, a 4-wire system with AC run and DC reset, a two wire system with actual time reset, or one you haven't seen for years... this is the clock for you. Right out of the box, this clock can distinguish and accept the most popular reset formats. For those legacy reset formats, they can be selected from an always growing list of supported formats. This premium series also offers NATSCO's exclusive automatic dim feature that decreases the brightness to compensate for low ambient light levels associated with artistic and video productions. This not only provides a pleasant brightness level, but also saves energy during nighttime hours. Nine brightness levels may be selected to satisfy the brightest locations. 12 hour or 24 hour time format is selectable at each clock as well as 50/60hz for accurate timekeeping. Stand-alone operation without a master clock is also made possible using the included time setting buttons. 24VAC units are available in attractive 4" or 2.25" high visibility, wide-bar digits. Compatible with 120VAC powered systems when the appropriate 24VAC transformer is mounted at each clock or double face unit. The durable steel housing, plug-in connectors and universal mounting plate simplify installation. An optional low profile surface box allows for surface mounted conduit entry. Powder grey finish standard, other colors upon request.
