Description
The 4003 series solid state power controllers will switch up to 60 Amps 3 phase,
600Vac. The Vac input unit can easily replace any mercury or magnetic
contactors. The Vdc input is
compatible with existing SCRs and will work with a variety of process
controllers.
The 4003 series solid state power controllers combine Chromalox’s years of
SCR technology experience and know-how with new components and packaging
technologies to deliver reliable and easy-to-install SCR components. The 4003
series power controllers are compactly packaged to allow for fast and easy
DIN-rail or sub-panel mounting, with wiring terminals easily accessible from the
front. The depth and height of all controllers in the 4003 series are
consistent, optimizing the mounting and wiring of mixed controller types.
Optional heatsink thermostat protects the SCRs from failure.
Quick, Easy Installation
The 4003 series power controllers are compactly packaged to allow for fast
and easy DIN-rail or sub-panel mounting, with wiring terminals easily accessible
from the front.
Electrical and Safety Features
• Ground Potential Heatsink
• SCR to Heatsink Isolation
• SCR resistant to Electrical Spikes, PIV up to 1600V
Minimal Electrical Noise
The dependable back to back SCRs fire at the zero-crossover (zero voltage)
point in the sine wave. This minimizes both RFI and EMI that can create havoc
for other electronic equipment in a plant.
