PEM1400 series
Datasheet
The PEM1400 series is the world’s smallest full power IEEE802.3af compliant Power Over Ethernet (PoE)Powered Device (PD) module delivering up to 12.95W of power in all output voltage ratings.
Features
- Low-Cost IEEE 802.3af PD Module
- High Efficiency
- Ultra Compact Size
- Low EMI
- 3.3V, 5V, 12V DC output voltage models
- General Details
With size of 35mm x 14mm, and a footprint of 409 mm², the PEM1400 is the world’s smallest IEEE802.3af compliant Power Over Ethernet (PoE) PD extraction module
The module delivers up to 12.95 watts of power when sourced from an IEEE 802.3af compliant Power Sourcing Equipment (PSE) using CAT5 or higher Ethernet cable. The module can deliver a full load start-up at input voltages as low as 36 volts.
The ultra-low cost PEM1400 is available in 12V, 5V, and 3.3V variants. It features a high efficiency DC-DC converter, frequency dithering to reduce EMI and noise, an on-board output “pi” filter for low ripple output and in-built overload and output short-circuit protection.
The PEM1400 series provides a quick, easy, and low cost method for Ethernet equipment manufacturers to “PoE enable” their equipment.
