Manager’s Insight

This power supply is a workhorse for 24 V systems. Its wide input range handles unstable grids. The overload capability protects downstream devices. For critical plants, keep a spare unit to minimize downtime.

Expert Review

Well‑built with solid EMC performance. The adjustable output allows fine‑tuning for sensitive loads. Its compact design saves panel space. Reliable choice for both OEM and retrofit projects.

Frequently Asked Questions

• Can I use this supply at 500 V AC input?
  Yes, it accepts 176‑550 V AC (switch set to 230‑500 V position).
• How do I set the output voltage?
  Turn the potentiometer on the front face to adjust between 24‑28.8 V.
• What happens during a short circuit?
  It limits current to 5.5 A or latches off (red LED). Reset by cycling input power.
• Is parallel connection allowed?
  Yes, up to 2 units can be paralleled for increased current. Use identical models.
• What is the storage temperature range?
  ‑40 °C to +85 °C, non‑condensing humidity.

Selection Guide & Tips

• For 5 A continuous load: choose this model (6EP1333‑3BA00)
• For higher current: parallel two units or select 10 A variant
• For harsh environments: add a buffer module to bridge voltage dips
• Check input voltage range before installation to avoid damage
• Use recommended circuit breakers (e.g., 3RV2011‑1EA10 for 230 V)

Warranty & Shipping

• Warranty: 12 months against defects
• Dispatch: 12‑24 hours after order
• Carriers: FedEx, UPS, DHL (tracking provided)
