When our standard equipment solutions don’t meet your design, our Engineering Team can adapt or create a system to fit your requirements.
AC General offers a 400 Hz three phase and single phase PDU rated at 20A service. The power input connector is Non-NEMA Hubbell Twist-Lock, commonly referred to as a “Variload TwistLock®” connector. The connector is UL498 Listed, and marked for 20A, 120/208V, 3PH, 400Hz service.
Note the single phase PDU also utilizes the same three phase connector, however only X-Phase, neutral, and ground wire are utilized.
For custom panels requiring more than 20A service, AC General will generally use an Amphenol MIL-5015 Type Standard Cylindrical Connector for the input and, often for the outputs.
A PDU equipped with a remote control option can be used without a remote control panel by connecting an AC General Bypass Plug into the REMOTE connector on the PDU rear panel.
Regardless of the PDU remote control configuration “R1” (momentary On and momentary Off switches) or “R” (single maintained On/Off switch), use Bypass Plug, P/N 400-029
When a Bypass Plug is used, all contactor-switched outputs are enabled whenever the main breaker is On.
Don’t hesitate to contact AC General with any questions in this area. There’s always a solution!
Absolutely. AC General specializes in adapting our products to meet your needs. Over the years, we’ve tailored our standard PDU products in hundreds of different ways. Most of the time, we can tailor a product with little or no NRE.
A Utility outlet (or Convenience outlet) is an output that provides power independent of the PDU control scheme. Generally, they are activated whenever the main breaker is switched ON. Utility outlets are used to power devices equipment that needs to remain ON such as computers, monitors, etc.
A branch is an electrical circuit taken from the AC Mains and controlled by one of two switching schemes.
A “Switched” branch is controlled by a contactor or power relay. Usually, the switching is controlled via a Remote Control Panel or other built-in means of opening/closing the branch.
An “Unswitched” branch is a circuit that remains ‘live’ whenever the main circuit breaker is active. It is independent of the contactor controlled switching scheme mentioned above. Typically, computers or other keep-alive equipment is plugged into an unswitched branch circuit.
Each circuit type is marked “Switched” or “Unswitched” on all PDU outputs.
Contact AC General via web, phone, or email and request a Return Material Authorization (RMA). The following items are needed before an RMA is granted:
A “U” is a mechanical measurement unit that equals 1.75 inches. 2U is 3.5 inches.
Generally, the serial number is located on the product side panel and/or the rear of the PDU.
Cables, Lockout Panels, and Control Panels don’t usually have a serial number
