It is specially designed for demanding applications in the harsh industrial automation field with an extended return voltage immunity making it suitable for safe operation against back feeding loads like decelerating motors and inductors. These units will deliver up to 480W over the full -40°C to +60°C ambient temperature range with only convection cooling. An extended power bonus of up to 576W at 45°C plus a power boost of up to 150% for 5s makes them suitable for powering highly inductive or capacitive loads. The unique and innovative modern design with 25° push-in connectors allows easy tool-less installation or replacement. The product is certified according to the global safety standards IEC/EN/UL 61010-1 and IEC/EN/UL/CSA 61010-2-201. Electromagnetic radiated and conducted emissions are compliant to heavy industrial EN 61000-6-3 Class B emission standard and EN 61000-6-2 immunity standard. |SELECTION GUIDE

Press the lower part of the device firmly against the rail until the device locks into position on the DIN rail. 4. To make sure it is securely locked in place, give the device a gentle shake. ## Release Option 1 (tool-less) **==> picture [265 x 142] intentionally omitted <==** **----- Start of picture text -----**

1. Press the unlock button on the top of the device to release the latch from the rail. 2. While pushing the button, slightly tilt the device forward. 3. Pull the device away from the DIN rail by pushing it up 4. Remove the power supply completely from the rail.

For vertical mounting the device should be installed with the input terminal on the bottom (standard orientation). For all other mounting orientations, the maximum output power must be reduced by 15% of the nominal power. No space between supplies is required. **==> picture [162 x 224] intentionally omitted <==** **----- Start of picture text -----**

## Parallel operation for redundancy 1+1 - 1) Adjust each power supply to the exact same output voltage with same load and cooling conditions. - 2) Use the same wire length and cable cross-section for each power supply (star connection) and energize all units at the same time to avoid triggering overload protection. - 3) It must be ensured that one of the power supply is able to provide the total required output power of the DC load to be supplied. - 4) In normal operation, each of the two power supplies will be utilized by up to 50%. - 5) ATTENTION: To prevent high reverse currents in the event of a secondary output fault, it is recommended to install a protective circuit at the output of each device when more than two power supplies are connected in parallel (e.g. decoupling diode or DC fuse). - Leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. **==> picture [23 x 7] intentionally omitted <==** **----- Start of picture text -----**

- Please Note: This basic redundancy configuration does not protect against internal short circuits on the secondary side. In such cases, the faulty unit may draw current from the remaining supplies, resulting in loss of output regulation. To prevent this, use redundancy modules with integrated decoupling elements. RECOM offers the RACPRO1-RD40 redundancy module as a suitable solution for this purpose: **==> picture [195 x 164] intentionally omitted <==** **----- Start of picture text -----**

## Series Operation - 1) Only use PSU with the same type and performance class with identical parameters. - 2) To increase the DC output voltage, connect 2 or more power supply units in series. - 3) Therefore, negative output terminal “-1” of the first power supply unit must be connected to the positive output terminal “+1” of the second power supply unit and routed to the load. Depending on the common output-side earth reference point of the power supply unit, see below table/figures as example. - 4) ATTENTION: Leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. **==> picture [540 x 312] intentionally omitted <==** **----- Start of picture text -----**
