Designed for installation in the control cabinet front
This saves you valuable space on the mounting plate as well as valuable wiring time thanks to our prefabricated compact power modules
LM4i, 4-fach Triacmodul
The 4-channel power module is designed for switching AC voltages to resistive loads, with zero-voltage switching up to 16A per channel. It is designed for installation in the front of the control cabinet. The external heat sink provides the necessary heat dissipation, and a seal guarantees protection class IP54. The triacs are protected by integrated, internally accessible super-fast fuses, eliminating the need for additional assembly and wiring. The mains voltage can be supplied separately to each channel or to multiple channels via optional bridges, enabling individual phase distribution. The outputs are connected via 6.3mm flat connectors. All inputs and outputs are pluggable, and connections are made via pre-assembled cables. An optional internal cover provides the necessary touch protection.
