AMETEK: HDR Power Systems, Inc. Model SCZF1

MODEL SCZF1 SERIES
POWER CONTROLS

Single-Phase Zero-Fired Models
Rated 15 - 65 Amperes

The Model SCZF1 Series of single-phase, zero fired SSR (Solid-State Relay) Power Controls are designed for the exacting needs of the ceramic and semiconductor industries as well as standard resistance heating applications.

By combining the European "touchsafe" design with the optional load failure alarm, the SCZF1 serves as the perfect choice for lower current applications.

The optional Load Failure (LF) Alarm includes non-isolated 0-5 Vdc signals proportional to the output voltage and current.

A Power On indicator (red) and a Command Signal indicator (green) are provided to help trouble shooting. The inclusion of a control transformer and I2T fuse sets it apart from most SSR type power controls.
