Power Systems Products
PD SYSTEMS is a Service-Disabled Veteran-Owned Small Business (SDVOSB) specializing in Engineering, Logistics, and Acquisition Support. PD Systems is an integrator and provider of power generation and power distribution equipment hardware and software, and is well versed at developing integrated power solutions for complex military customer requirements.
PD Systems possesses all the capabilities required to successfully design, integrate, produce, and maintain power generation and distribution products. We possess personnel that comprise management, engineering, and manufacturing individual that are leaders, engineers, production managers, and logisticians experienced in the delivery of commercial and military power generation, power distribution as well as aircraft ground support equipment. PD Systems ISO Certified Quality Company and our use of lean technology will:
• Ensure accountability for quality performance and project control
• Provide a 24-month warranty and pass through of OEM warranties/ 24-hour call support Provide 24×7 “one stop shop” for all existing products as well newly developed requests
PD Systems’ products include providing reliable and durable power in the form of power Generator sets ranging in size from 2.5KW to 6.7MW power plants, transportable and fully operational through both on-board and remote controls as well as extreme military environmental conditions.
We provide products that generate prime power and provide through Primary Switching Centers (PSC) both Secondary (Secondary Distribution Centers) and tertiary distribution (15KW, 25KW, 30KW, 60KW, 100KW, and 200KW Power Distribution Panels) to support both 50 and 60-Hertz operations. Our products use a modular design and our equipment facilities allow us to meet user defined configurations to meet specific electrical power generation and distribution requirements. This includes needs ranging from small KW loads to fullsize, integrated “standby” power systems.
In summary, PD Systems offers full service solutions. Our hardware developers and integrators have successful cradle-to-grave experience in hardware engineering, production, system integration, testing and Integrated Logistics Support (ILS).
PD Systems can support your Power Generation and Distribution Requirements. Feel free to call or e-mail us, we’d be glad to help!

Senior Vice President,
PD Systems offers a wide range of Trailer and Skid Base Mounted Load Bank solutions that meet or exceed all mission capability requirements, with a significantly low mission capability risk rating. The 1250KVA load bank is trailer mounted, compact, and designed and packaged for military applications.
The PD Systems 1250KVA load bank is designed to provide high capability resistive and reactive loading of AC power sysyems such as diesel generator sets, turbines, or Uninterruptible Power Supplies (UPS).
Many specifications and local codes demand that such testing be performed at less than unity power factor, typically 0.8 PF lagging. To achieve a 0.8 power factor, the load banks combine resistive load (KW) with reactive load (KVAR). This combination provides a true test of the actual generator or UPS nameplate rating (KVA) and simulates a “real-world” load.
The load bank incorporates state-of-the-art load bank design using heavy-duty resistance elements. Thr resistor elements, reactive elements, blowers, and controls are all manufactured from the highest quality components available for long life and reliability.
Generator connections are made to the load banks via the 200 amp load break or 600 amp dead break connectors. The 4160 VAC is then stepped down to 480 VAC for loading the resistive and reactive elements. There are two (2) load break input connects per phase on this model. Shore power or generator power may be used to provide control power to the load bank controls via control panel selection.
Construction: The load bank consists of a rugged enclouser housing the resistive and reactive componenent, blowers, associated contrils and interconnections. Each assemebly(ressistive and reactive) is hoised independently in its own section.
Resistor Elements: The resistive elecments are manufactured from corrosion-resistant chromlum alloy wire and are fully sippoortted on stainless steel rods for long life. The ise of continuous stainless steel ribbon in manufacturing eliminates welds.
Reactive Elements: Te reactive elements are of non-saturating single and three-phase iron-core construction impregnated with hign dielectc varnish. Smaller KVAR elecments than the standard 37.5KW elements are avaliable for a more finith KVAR control adn better power factory accuracy.
Control Power: 120 VAC, 1-Phase, 60 Hz provided by an integral control power transformaer.
Metering: Digital metering wit data logging is provided to measure voltage, current, frequncy, KW, kVAR, and power factor.
Colling: The resistive elecments are colled by integrally mounted blower motors-eac rated 460 VAC, 3-Phase, 60 Hz.
Controls: The Load bank featured both local and remote load control. The remote control panel provides load metering. element conrol, fan control, individual elment overcurren indication, and general protective indications.
Protection: The Load bank features branch circuit protection an all load steps and over temperature protection. Air switches on the blowers are electrically interlocked to remove load if the airflow is not sufficient to provide proper colling.
Transportability: PD Systems’ Load Banks meet transpotability requirements without shoring on C-17 aircraft, based on design criteria of MIL-HDBK-1791.
