Power & Electricals

Every control panel needs a clean, regulated 24 VDC bus to power the PLC, the HMI, sensors, and indicators. DIN-rail switched-mode power supplies in the 60–480 W range (OMRON S8VK / S8VS, Siemens SITOP, Allen-Bradley 1606, Phoenix Contact QUINT) are the workhorse here. Above that — large CNC drives and rack systems — you'll see purpose-built power modules sized for the specific equipment.

Switching and protection cover everything from the IEC contactors that switch motors on and off (Schneider TeSys, Siemens SIRIUS, Allen-Bradley 100-series), to circuit breakers (MCBs / MCCBs / motor protection switches) that protect against overcurrent and short circuits, to control relays that interface low-current PLC outputs with higher-current loads. Sizing here is grounded in IEC 60947 and the local distribution-board standards.

On the metering side, integrated power-quality meters (Siemens SENTRON PAC, Schneider PowerLogic) capture not just kWh but harmonics, THD, voltage imbalance and demand peaks — useful both for energy-cost reporting and as an early warning of upstream supply issues. We stock the full electrical infrastructure for control panels — drop us a list of parts and we'll quote against it.
