Wall-mount power supply PSW1250

AC/DCregulatedadjustable

The Power Supply type PSW1250 is a stainless steel AISI 304 unit. The supply provides 24Vdc, 50 A output. PSW1250 units can be paralleled, with load sharing circuits, which distribute current load equally to each power supply to increase reliability and reduce internal power dissipation. The supply accepts AC power sources with nominal voltage range 110 to 240 Vac (±10%).SIL 3 for NE Load according to IEC 61508:2010, with single PSW1250 module or more PSW1250 modules in redundant configuration (see ISM0220 for more information).SIL 1 for ND Load according to IEC 61508:2010, with single PSW1250 module (see ISM0220 for more information).SIL 2 for ND Load according to IEC 61508:2010, with more PSW1250 modules in redundant configuration (see ISM0220 for more information).Systematic capability SIL 3.Power factor correction.Installation in Zone 2/Div. 2 hazardous locations.EMC Compatibility to EN61000-6-2, EN61000-6-4.ATEX, IECEx, UL & C-UL, TÜV Certification.TÜV Functional Safety Certification.Tested for maritime applications.Highly regulated output of 24 Vdc, 50 A, for PSW1250 module.Under and over voltage alarm monitoring.3 over voltage redundant protections.Redundant parallel connections with load sharing.Reduces power dissipation (in parallel/redundant configuration) by replacing a Schottky diode with Mosfet Active Ideal Diode.89% efficiency @230 Vac input and 24 Vdc output and full load.Fan speed control depending on ambient temperature and output power.High load fuse breaking capability without interrupting operations.Tropicalization for electronic components.Technical Specifications:AC Input voltage: nominal 110 to 240 Vac (±10%), frequency range 48 to 62 Hz.Power Factor Correction (AC input): 0.98 typ.@230Vac, 0.995 typ.@115Vac, full load.Efficiency @24Vdc out (full load): better than 89% @ 230 Vac and 86% @ 115 Vac.Max. internal power dissipation @24Vdc out (full load): 150 W @ 230 Vac; 195 W @ 115 Vac.AC input current (sinusoidal at full load) @24Vdc out: 14.2 A @ 100 Vac, 12.2 A @ 115 Vac, 6.1 A @ 230 Vac.Inrush current: 37 A peak @ 264 Vac; 32 A peak @ 230 Vac; 16 A peak @ 115 Vac.AC input connection: screw terminal blocks suitable for 4mm² wires.Input to Output isolation: 2500 Vrms (routine test).Input to Earth-Ground isolation: 1500 Vrms (routine test).Earth-Ground to Output isolation: 500 Vrms (routine test).Output or Earth-Ground to Fault contact isolation: 500 Vrms (routine test).Output voltage: 24 Vdc (adjustable from 21 to 28 Vdc).Regulation: 0.4% for a 100% load change.Stability: 0.01% for a 20% line voltage change.Ripple: ≤ 250 mVpp.Output current: 50 A nominal (@24Vdc out).
