The PU20 and PU21 feature redundant power monitoring and inverse
current protection
BLUE BELL, Pa. July 2014 – MEN Micro Inc., a world-renowned
provider of embedded computing and I/O solutions for mission-critical
industrial, mobile and harsh environment applications, now offers two
power supply units, the PU20 (DC) and the PU21 (AC), for reliable
computer power sourcing required in onboard or wayside railway
applications as well as other harsh environment applications. The
redundant power monitoring and inverse current protection offered by
these units help to secure a constant output of power in harsh
environments.
Designed with conformal coated electronics as well as a robust H15
rear connector, these new units are protected from both moisture and
vibration. Both the PU20 and PU21 offer high functional reliability.
Should power be lost for any reason, voltage is evenly distributed to
the remaining working units, ensuring a consistent and constant
current power output.
Developed according to EN 50155, both units are able to
accommodate different voltage inputs on trains as well as on the
tracks. The PU20 automatically detects input voltage for 24, 72 and
110 VDC and can be manually configured for 36, 48, 74 and 96
VDC. The PU21 offers a wide input voltage range from 100 VAC to
240 VAC.
Output power for each unit is 125 W at the standard output voltage of 5
V; while standby power is 5 W at 5 V, allowing users to start the power
supply units with a wireless connection. An integrated microcontroller
monitors the ports, voltage as well as temperature to ensure safety.
These pluggable power supplies are offered in single Eurocard format
(3U) and are designed for use in 19” systems such as CompactPCI,
CompactPCI Serial and VMEbus, and need only 6 HP at the front.
They have an extended operating temperature of -40°C to +85°C.
Equipped for SIL applications, these new fail-safe units are also
certified to S-9401.
