III. Core features of the product

Conductive cooling design: relies on the bottom metal substrate to dissipate heat, no need for fans, can be used in sealed enclosures, suitable for equipment enclosures with no convective heat dissipation, outdoor sealed equipment has obvious advantagesdocs.rs-on...。

Built-in PFC power factor correction to reduce grid harmonic interference.

Ultra-thin full brick, standardized pins, compatible with industry Full-Brick layout, easy to replace.

Supports remote on / off control, external control module can start and stop.

The output voltage can be fine-tuned with a resistor, suitable for the power supply requirements of 24V-28V industrial equipment.

Note: This module requires external input protection and EMI filtering components to fully meet the EMC standard. It cannot be used directly on the bare module. TDK Produc...。

IV. Typical Application Scenarios

Communication equipment: industrial switch, remote radio unit, communication base station closed cabinet power supply

Industrial equipment: industrial control cabinet, test instrument, closed-type industrial control machine

Outdoor equipment: outdoor cabinet, security, sealed box for unmanned equipment (no fan cooling)

Energy storage, 28V industrial system power supply, replace traditional 28V complete power supply

V. Comparison and differentiation of the same series

PFE500 SA-28: SA simplified version, does not support module parallel expansion, no auxiliary power output, low cost, mainstream large-scale selection;

PFE500-28: F enhanced version, supports multi-module parallel connection, with 12V auxiliary output, different pin definition, higher price;

PFE300 SA-28: Same package 300W version, output 10.8 A, power reduction versiondocs.rs-on...。

VI. Summary of advantages and disadvantages
