Power Controllers

Variable transformers and Triac controllers for manual, 0-100% adjustable heater power.

Controls & Accessories

Manual Voltage Control for Heating Elements

For voltage control, a variable transformer or solid-state Triac controller may be used. HTS/Amptek® power controllers give you smooth, manually adjustable output — from the LC-Z-120 and LC-Z-240 Triac controllers to bench-top Variac transformers.

Power controllers are the simple, rugged choice when an application calls for adjustable heat without closed-loop temperature sensing.

The Range

Triac & Variac Options

Triac Controllers

Solid-state LC-Z Triac controllers adjust heater power smoothly from 0% to 100% — a compact, dependable way to control voltage on heating tapes and small heaters.

Variable Transformers (Variac)

Bench-top variable transformers deliver clean, manually adjustable output voltage. The classic laboratory solution for controlling heating tape output.

When to Use Power Control

For voltage control without a temperature sensor, a variable transformer or solid-state Triac controller is the right tool. For precise closed-loop temperature control, step up to a PID controller.
