SynQor Releases an Advanced 28 Vdc Input 3U VPX With Extended Hold-Up (VPX-3U-DC28TH- 001)

BOXBOROUGH, Mass., March 26, 2024 (Newswire.com) - SynQor^®, Inc., announces its latest 28 Vdc input VPX power supply featuring extended hold-up designed for critical aerospace and shipboard applications: the VPX-3U-DC28TH. This 3U VPX adheres to VITA 46 standards, enabling military and industrial designers to power VITA 62 chassis with the latest flexible, efficient, and reliable VPX technology. Notably, a 50ms hold-up feature has been integrated into this VPX to meet the power interruption and drop-off requirements set out by MIL-STD-704F.

The VPX-3U-DC28TH is extremely efficient at 91% and is able to deliver 500 W throughout its full temperature range of -40 to 85 °C (at the wedge-locks). It is also equipped with an advanced set of features such as an integrated EMI filter, conduction cooling, six output voltages with reverse polarity, over-voltage, under voltage, short circuit, and over-temperature protections. In addition, this VPX supports I2C communications (IPMI, PMBus, VITA 46.11). The power supply’s standard VS1, VS2, and VS3 outputs can be load-shared on a standard VITA 62 chassis. Designed for the most demanding military and commercial applications the VPX-3U-DC28TH meets VITA 46, 47, 62, MIL-STD-704F, 461F, and 810G standards.

Features: 

• Six outputs (VS1: +12 V; VS2: +3.3 V; VS3: +5 V; Aux: +3.3 V, +12 V and -12 V)
• 500 W output power over a temperature operating range: -40 to 85 °C
• Extended hold-up time of over 50ms at 500 W
• Integrated EMI filter with reverse polarity
