In stock at authorised distributor DigiKey are the TDK-Lambda TPS4500-92/184 single or dual-output industrial power supplies. They have a 4500W rating.
The outputs can be configured to share loads in any proportion, up to the rated output specifications, and are designed to operate in series or parallel to increase the output voltage or power.
Capable of operating from a high-voltage three-phase input in a 360VAC to 528VAC Delta or wye configuration, the TPS4500 series can be used in multiple applications, including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, lasers, and RF power amplifiers. The high-voltage, three-phase input eliminates the need for costly step-down transformers and helps balance phase load current.
The TPS4500 series is fully featured with isolated AC fail, DC good, and dropped phase signals, remote on/off, remote sense, and a 12V, 0.3A standby supply. The PMBus communications interface enables comprehensive remote monitoring and control.
It provides real-time visibility into key parameters, including output voltage, output current, internal temperature, status signals, and fan speed. Additionally, PMBus allows programming of critical settings, including output voltage, overcurrent limit, and remote on/off functionality.
The power supply has a typical efficiency of 93% and can start in temperatures as low as -40°C and operate in ambient temperatures from -10°C to +70°C, derating linearly from 100% to 80% load from -50°C to +60°C, and from 80% to 55% at +70°C. The TPS4500 series enclosure measures 107mm x 85mm x 335mm (W x H x D), making it suitable for 2U high racking systems.
Safety certifications include IEC/UL/CSA/EN62368-1 and carry the CE and UKCA marking for the low voltage, EMC, and RoHS directives. The units also comply with EN55032-A conducted and radiated emissions standards in the end system, meet IEC 61000-4 immunity standards, plus SEMI F47-0706 at 480 VAC nominal (Criteria B).
The power supply has 3,000 VAC input to output, 2,000 VAC input to ground, and 500 VDC output to ground isolation. The TPS4500 series is designed to meet MIL-STD-810H, Method 514.8, Proc I, Category 1, 10 (vibration), and MIL-STD-810H, Method 516.8, Procedure I, IV (logistics) and VI (shock) standards, ensuring exceptional durability and reliability in harsh environments.
