Control Power & Power Supplies

WPS switch-mode supplies, control power transformers, and buffering accessories that keep automation cabinets energized.

Reliable control power underpins every automation project. WEG delivers compact switch-mode supplies, multi-tap control transformers, redundancy modules, and energy storage options that maintain 24 VDC rails through brownouts and motor inrush. Gross Automation engineers design redundant architectures, specify protection, and validate loading so your PLCs, HMIs, and safety circuits stay online.

Key Differentiators

Wide Input Ranges

Auto-sensing AC and DC inputs accommodate global voltages without selector switches.

Redundancy Ready

Oring modules and buffer packs support parallel supply operation for critical loads.

Diagnostics Built In

DC OK contacts, front LEDs, and remote monitoring outputs simplify panel maintenance.

Global Certifications

UL, CSA, CE, and cULus approvals keep machine exports compliant and inspection ready.

Control Power Building Blocks

WPS Switch-Mode Supplies

  • 15–480 W DIN-rail supplies with convection cooling and high efficiency.
  • 120/230 VAC or 3-phase 380–480 VAC inputs for global installations.
  • Adjustable 24 VDC outputs with trim potentiometers and remote sense terminals.
  • Conformal-coated PCBs for vibration and temperature resilience.

Control Power Transformers

  • Multi-tap primaries support 208/230/460 VAC supplies with 120 or 24 VAC secondaries.
  • Factory-installed fuse blocks and finger-safe covers streamline UL508A compliance.
  • Class H insulation and copper windings manage high inrush loads.
  • Optional electrostatic shields reduce noise on sensitive PLC circuits.

Energy Storage & Redundancy

  • Buffer modules ride through outages up to 20 seconds with maintenance-free capacitors.
  • Redundancy modules provide load sharing and fault isolation between supplies.
  • DC UPS options pair with sealed lead-acid or lithium packs for extended runtime.
  • Diagnostic relays alert PLCs to impending undervoltage or module failure.
