This module converts single-phase AC input (120\/230 V automatic range selection) to a regulated 24 V DC output at 5 A. With an efficiency of 88% and a typical power loss of only 16 W, it offers excellent energy savings and long-term cost benefits. The unit includes overvoltage protection, short-circuit proof output with constant current characteristic, and a green LED for status indication. Its compact design (50 x 125 x 120 mm) snaps onto standard DIN rails, making installation straightforward.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e85–132 V AC \/ 170–264 V AC (automatic range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC (adjustable 22.8–28 V via potentiometer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Output Current\u003c\/td\u003e\n\u003ctd\u003e5 A (0–6 A up to +45°C, derating above +60°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency\u003c\/td\u003e\n\u003ctd\u003e88%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Loss (typical)\u003c\/td\u003e\n\u003ctd\u003e16 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMTBF at 40°C\u003c\/td\u003e\n\u003ctd\u003e1,998,441 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResidual Ripple (max)\u003c\/td\u003e\n\u003ctd\u003e150 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShort-term Overload Current\u003c\/td\u003e\n\u003ctd\u003e18 A (typical) for 800 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Class\u003c\/td\u003e\n\u003ctd\u003eIP20, Class I\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, cULus, UKCA, EAC, CB, BIS, shipbuilding approval (BV, DNV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eThe \u003cstrong\u003eSiemens 6EP1333-2BA20\u003c\/strong\u003e also features a relay contact (NO, 60 V DC\/0.3 A) for voltage OK signaling, and buffering time of at least 20 ms during power failure. Galvanic isolation between input and output ensures safety extra-low voltage per EN 60950-1 and EN 50178.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThis power supply is ideal for control cabinets, PLC systems, and industrial sensors requiring a stable 24 V DC source. For example, in a manufacturing line with frequent voltage fluctuations, the \u003cstrong\u003eSiemens 6EP1333-2BA20\u003c\/strong\u003e maintains output regulation within 3% overall tolerance, preventing downtime. Its ability to deliver 144 W of active power supports multiple loads, and the adjustable output allows fine-tuning for critical equipment. The long MTBF (over 1.9 million hours) reduces replacement costs, aligning with cost-benefit goals.\u003c\/p\u003e\u003ch2\u003eInstallation and Mounting\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSiemens 6EP1333-2BA20\u003c\/strong\u003e snaps onto a DIN rail (EN 60715 35x7.5\/15). Required clearances: 50 mm top and bottom, 0 mm left and right. Use screw terminals for input (L, N, PE: 0.5–2.5 mm²), output (+, –: two terminals each), and signaling (two terminals). Ensure natural convection cooling; ambient temperature range -25 to +70°C. No wall or S7 rail mounting is supported.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eWith an MTBF of 1,998,441 hours at 40°C, the \u003cstrong\u003eSiemens 6EP1333-2BA20\u003c\/strong\u003e requires minimal maintenance. The unit is short-circuit proof and includes overvoltage protection (Vout \u0026lt; 33 V). Regularly inspect the green LED and relay contact for correct operation. Keep ventilation slots clear; derating applies above +60°C (1.6%\/K). The enclosure meets IP20, so protect from dust and moisture.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eBefore purchasing, verify input voltage compatibility (120\/230 V AC, 50\/60 Hz) and ensure the output current meets your load (5 A continuous, up to 6 A below +45°C). For higher power, up to two units can be paralleled. Recommended upstream protection: miniature circuit breaker, 6 A characteristic C. For accessories, consider buffer modules and the device identification label (3RT1900-1SB20).
