- Small DC motors and drives
- Test and measurement equipment
- Packaging and material handling machines
Professional FAQ
- What is the derating curve for this unit?
Full 20 A from -25 °C to +45 °C. Reduce by 2.5% per °C above +45 °C, up to +70 °C.
- Can I use it with a 110 V supply?
Yes, it works from 85 V AC. At 110 V, input current is about 5.5 A.
- Is the output isolated from the input?
Yes, full galvanic isolation. The output is SELV rated.
- How to connect multiple units in parallel?
Connect outputs in parallel (same voltage). Use up to 2 units. Ensure identical settings.
- What if the green LED is blinking?
This model has steady green for normal. Blinking may indicate overload or fault – check load and wiring.
Experience-based Q&A
- My unit trips the breaker on startup.
The inrush current can be high (45 A). Use a C-characteristic breaker (not B).
- Output voltage shows 22 V, not 24 V.
Adjust the potentiometer on the front. It can be set from 22.8 to 26.4 V.
- Can this unit run at full load in a closed cabinet?
Ensure 50 mm clearance top/bottom. For high ambient, derate or add forced cooling.
Selection Guide (Buying Tips)
- Check your total load current – stay under 20 A (or 16 A at 60 °C).
- For higher power, use two units in parallel (max 40 A).
- If your grid is unstable, the wide input range helps (85-264 V AC).
- For outdoor or wet areas, choose a higher IP rated supply.
- Always use the recommended MCB (10 A, C-curve) to avoid nuisance trips.
