The Load Bank Experts
The team at Trystar have been manufacturing high-capacity resistive loads for almost 20 years. Trystar leads the market with innovative designs in AC, Resistive Reactive, Medium Voltage and DC applications.
Built to Last
The DC Series enclosures are constructed of galvanized steel with the highest quality durable powder-coat paint finish, and external stainless steel fasteners. The load bank can be designed for permanent installation or can be of portable type (consult factory for available sizes). For permanent installations, the enclosure is of outdoor construction, to be installed and operated on a floor, roof-top, or concrete pad. Portable load banks provide ease of positioning with moving handles and heavy-duty casters. Tie-down provisions allow for secure transportation to and from job sites. Larger load banks have forklift channels within the base for ease of lifting and handling during installation.
Operator Controls

Operator Protection
The DC Series Load Bank comes equipped with an Emergency-Stop push button allowing the operator to take the unit off-line should a critical hard-stop condition occur. Blower On, Motor Overload, Air-Flow Failure, and Over-temperature circuits disable all load steps during a fault condition with operator visual indicators, while the Load Dump circuit provides the operator visual indication if all load steps have been removed.
