120 tot 480 W DIN-rail Voedingen Gecertificeerd voor Explosiegevaarlijke en Mariene Toepassingen
Geplaatst : 08 Sep 2015
TDK Corporation announces the introduction of three additional models to TDK-Lambda’s DRF series of DIN rail power supplies. Rated at 120W, 240W and 480W power levels, the new units have received certification for potentially explosive atmospheres and marine applications.
The DRF120-24-1/HL, DRF240-24-1/HL and DRF480-24-1/HL products have been tested to IEC/EN 60079-0:2011, IEC/EN 60079-15:2010 and Guidelines for the Performance of Type Approvals – Test Requirements for Electrical / Electronic Equipment and Systems (VI-7-2). All three models now display IECEx, ATEX and DNV-GL nomenclature accordingly.
Operating from a wide range input of 85 to 265Vac with a peak of 300Vac for 5 seconds, the units can deliver 24V at 5A, 10A or 20A. A peak power capability of 150% for 4s, along with a constant current overload characteristic, makes the DRF/HL series ideal for many challenging industrial applications.
For uniformity, all models share a common height and depth measurement of 123.4 x 115.4mm, with widths of just 36.5, 49 and 82mm according to the rated output power. The DRF/HL series will operate at full load in an ambient of -25 to +60oC, derating to 75% load at 70oC, with efficiency levels of up to 94%. Off-load power draw is below 0.5W or 0.75W (model dependent).
Features include parallel capability, remote on/off, a DC Good relay, output voltage programming and conformal-coated printed circuit boards. The DRF/HL models are fully protected against over-voltage, over-current and over-temperature conditions.
In addition the DRF/HL series is also certified to IEC/EN 60950-1 (2nd Ed.), UL/CSA 60950-1 and UL 508. The CE mark now covers the ATEX Directive 94/9/EC as well as the LV Directive, EMC Directive and RoHS Directive. The DIN rail power supplies meet EN 55022-B and CISPR22-B for conducted and radiated EMI and include a five-year warranty.
