Description
The ARFDin output voltage is stabilized to within ±5 %, and efficiency exceeds 83 %. The input accepts a single-phase mains of 90–264 V AC, and some models are designed for a three-phase 230/400 V input. The UL, C-UL and CE marking simplifies acceptance of cabinets shipped to North America and the EU. The CRFw chargers of 50–120 W maintain buffer batteries in small systems. CRFD works with 12 or 24 V batteries of AGM, GEL, calcium and lithium types, so one device covers most starter and buffer batteries.
How to choose
First determine the DC bus voltage: 24 V is typical for PLCs and sensors, 110 V for relay protection circuits. Choose the ARFDin power with a margin over the sum of the consumers, within 60–1500 W. If the cabinet needs an AC UPS rather than a DC source, look at the online IRIS+ of 1–3 kVA.

FAQ
What output voltages do the ARFDin power supplies have?
12, 24, 48 and 110 V DC are available with ±5 % stabilization, at power from 60 to 1500 W.
What mains do the ARFDin supplies run from?
Single-phase models accept 90–264 V AC, and there are also versions with a three-phase 230/400 V input.
Which batteries does CRFD charge?
CRFD charges 12 and 24 V batteries of the AGM, GEL, calcium and lithium types.
What is the efficiency of the ARFDin DIN units?
Efficiency is above 83 %, which should be taken into account when calculating heat release in the automation cabinet.
What power do the CRFw chargers have?
CRFw are made with a power of 50–120 W, which is enough to top up buffer batteries of security systems and small automation cabinets.
