EVR Series – 25A 230VAC Burst Fire Power Regulator

Description

The EVR range of triac ‘Mini Stacks’ are available for single phase, 230V applications. Other voltage supplies are also available. They can control loads of up to 25A, with a number of signal control options. The stacks are assembled to suit the final load, with options of phase angle or burst firing control. All EVR triac stacks come complete with appropriately rated High Speed semiconductor fuses and an integral heatsink.

Applications: The EVR Thyristor stacks are perfect for controlling heaters, ovens, dryers, air curtains, hot plates, and heating and ventilation systems. The SCR solid-state phase angle power handling provides smooth proportional control for diverse industrial processes, including furnaces, electroplating, controlled rectifiers, and transformers.

Features:

• Single Entry Cable Gland: Simplifies installation.
• Massive 0.3°C/Watt Earthed Heatsink: Ensures efficient heat dissipation.
• Control Options: Available in phase angle or burst firing versions.
