This document is an application note for TDK-Lambda PF/PF-A series of power supplies, introducing the features and characteristics of the products and application circuits.
This document provides technical guidance for designing circuits using the TDK-Lambda PF/PF-A series power modules. It details requirements for input/output fuses, capacitor selection for ripple voltage and holdup time, and specific connection procedures for PH series connections.
The notes also explain operational parameters such as input voltage ranges, output current capabilities, efficiency variations based on input voltage, and derating curves for high-temperature environments.
| Nominal Output Voltage (Standard) | 360VDC |
|---|---|
| Input Voltage Range | 85~265VAC |
| Input Frequency Range | 47~63Hz |
| PF1000/PF1000A-360 Max Power (100VAC) | 1000W |
| PF500/PF500A-360 Max Power (200VAC) | 750W |
| PF1000/PF1000A-360 Max Power (200VAC) | 1500W |
| PFHC Operation Limit | Above 255VAC |
A fast blow type external fuse should be used to protect the load from damage.
It is determined by the formula Co = Pout / [2 * f * Vinx * XV, xn], ensuring peak-to-peak ripple is less than 15Vpk-pk.
A 4700pF capacitor should be placed on the input side between the -V terminal and baseplate (FG).
