Murata Power Solutions today announced the ULT series of
isolated 30 Watt DC/DC converters available in a miniature 1/32 brick industry
standard Distributed-power Open Standards Alliance (DOSA) compatible open frame
package. Measuring just 19.1 x 23.4 x 8.89 mm, the ULT series takes up
significantly less board space than other 30W products on the market and is
available with either through-hole or surface mount option.
The ULT series has been designed with a wide (2:1) input
voltage range of 36 – 75 VDC to meet the requirements of 48V and 60V battery
back-up systems. The initial product release includes 12Vout, 5Vout, and
3.3Vout models with lower voltages to come in the near future. The maximum
output power of 30 W is available from the 12Vout model, with the 5V and 3.3V
models producing 25W. Line regulation is typically within +/- 0.1% of Vout
across all Vin conditions at full load. An external trim function allows the
output voltage to be trimmed by + 10 % to – 20% to accommodate losses. Input to
output isolation is certified to 1,500 V in accordance with the internationally
recognized safety standard EN/UL60950.
The ULT series offers features that include remote On/Off
control of either negative or positive logic, Vout trim and a remote sense
capability. In addition the converter has a number of protection features
including output short circuit protection, over temperature shutdown and input
under voltage lockout.
The ULT series was designed for a wide range of applications
including distributed power architectures in Industrial, Telecommunications,
Routing, Optical Networking, Wireless equipment and Microwave Radio/point to
point communications.
The ULT series is designed to operate in the most severe
outdoor environments with an operating ambient temperature range from -40 to
+85 degrees C.
