Oiltech Controls Review
- 95.4% efficiency is excellent for a 480 W three-phase supply. Heat load stays low.
- The 50% reserve handles motor and contactor peaks without a separate buffer.
- Spring terminals speed up wiring. Use ferrules on stranded wire.
- 48 V output suits telecom and drive control loads directly.
- Active status makes this a low-risk spare to hold on the shelf.
Oiltech Controls Insight
- Set output to 48.5 V for long DC runs. It covers cable drop.
- Check all three input phases at the terminal before power-up.
- Wire the DC OK contact to a PLC input for early fault flags.
- The 50% reserve is short-term only. Size continuous loads at 10 A.
- Log the adjusted output voltage on the panel door card.
Warranty and Dispatch
- 12-month warranty on all supplied units
- Dispatch within 24 to 28 hours after order confirmation
- Shipping by FedEx, UPS, and DHL
- Tracking number sent by email after dispatch
- Technical verification before shipment
FAQ
Q: What does the 50% power reserve mean in practice?
A: The unit can deliver short peaks well above 10 A, up to roughly 50% extra. Use it for motor inrush or contactor pull-in. Keep continuous loads at or below 10 A.
Q: Can I run this supply on 400 V AC three-phase?
A: Yes. The input range covers 380 to 480 V AC three-phase. Check phase balance at the terminals before you close the breaker.
Q: How should I set the 48 to 55 V adjustment range?
A: Match your load device input window first. For most 48 V systems, 48.5 V works well. It covers line drop without overstressing the load.
Q: Is the DC OK relay a communication interface?
A: No. It is a dry signal contact only. The supply has no fieldbus or protocol stack. Wire the contact to a PLC input for status.
Q: New or refurbished, which one should I pick?
A: This model is active, so new stock is readily available. Refurbished units suit budget spares. Confirm load test data, DC OK function, and the 12-month warranty before ordering.
