This, and a constant current overload characteristic, enables operation with capacitive and inductive loads. These power supplies also feature a very low energy inrush current upon initial start-up, reducing the nuisance tripping of input circuit breakers.<\/p>\n\n\n\n<p>The DRB three-phase series is suitable for a wide range of applications, including conventional switch cabinets, decentralised machinery and industrial systems, through to information and communications technology.<\/p>\n\n\n\n<p>Accepting a wide range input of 350 to 575Vac, the units are housed in a rugged metal case measuring just 55mm in width, 129mm height and 138.2mm deep, saving space on the DIN rail for other components. The high operating efficiency of up to 94% and low off-load power consumption, which can be reduced to &lt;2.3W when in standby mode using the remote on-off, reduces energy consumption. Lower power losses reduce internal heating and increase electrolytic capacitor lifetime.<\/p>\n\n\n\n<p>For higher power or redundant systems, the front panel DIP switch enables droop mode current sharing for parallel operation. All models have a wide adjustment range of 11.4 to 15V, (12V model), 22.5 to 29V (24V models) and 45 to 56V (48V model) to allow compensation for cable drops, ORing FETs or setting to non-standard output voltages. In addition to an LED indicator, a DC OK relay contact is available for remote monitoring and remote on\/off is possible by closed relay contact or &lt;4V input.<\/p>\n\n\n\n<p>Input to output isolation is 3,510Vac, input to ground 2210Vac and output to ground is 1,390Vac. The DRB models are convection cooled and rated for operation in -25 to +70\u00b0C ambient temperatures, with derating above 55\u00b0C.<\/p>\n\n\n\n<p>The units are certified to IEC\/EN\/UL\/CSA 62368-1, 61010-1, 61010-2-201 and are CE \/ UKCA marked to the Low Voltage, EMC and RoHS Directives. They meet EN 55011-B and CISPR11-B radiated and conducted emissions. The series also complies with EN 61000-3-2 (Class A) harmonic currents and IEC\/EN 61000-6-2 immunity standards.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TDK Corporation announces the addition of three-phase AC input models to the TDK-Lambda DRB series of DIN rail mount power supplies.\u00a0 Rated for continuous operation at 120W and 240W with 12V, 24V and 48V outputs, the units can deliver a peak of 144W and 288W for two seconds.
