Standard versions of model 11EZ are supplied with integral heatsinks and easy access terminals. The three-phase, solid-state relays for constant-resistance loads require a maintained external 120 VAC control signal for operation. Fuse kits (fuses and fuse blocks) are shipped loose with the units for remote mounting. They do not mount directly to relays. Other products in the company's line include single-phase, phase-angle solid-state SCR controls; three-phase, variable-voltage control solid-state SCR controls for transformer-coupled loads; SCR power controls with single-phase AC input; variable DC output to DC motors and inductive loads.
