XP Power announced additions to its SHP and
MHP series of high power density fan cooled AC-DC power supplies. The SHP1000
and MHP1000 are highly efficient, typically 85%, have a power density of up to
8.9 Watts/cubic inch and can provide 1000 W across the full input range of
90-264 VAC. Models with an output of 24 VDC or greater are capable of providing
up to 1200 W when used with an input of 180 VAC or greater. A range of 6 models
provide the single outputs of +12, +15, +24, +28, + 36 or +48 VDC. The output
is user adjustable within +/- 10% of nominal. A +5VDC, 1A always on output is
also provided for standby purposes.
The MHP1000 range meets the UL/IEC60601-1
safety specification for medical equipment as well as EN55022/EN55011 EMC
limits of Class B for conducted emissions and Class A for radiated. The SHP1000
range compiles with the UL/IEC60950-1 standards for ITE equipment, meets SEMI
F47 requirements and EN55022 EMC limits for Class B conducted and Class A
radiated.
These compact units, measuring just 242.6 x
149.8 x 61.0 mm (9.55 x 5.90 x 2.40 inches), can deliver full output power from
-20 to +50 degrees C and with derating up to +70 degrees C. The units are
capable of start up from as low as -40 degrees C. Both the SHP and MHP employ a
variable speed fan for noise reduction.
Available control signals include AC OK and
remote on/off. An active single wire current share capability is also provided
to allow sharing of loads across multiple units or for configuration of
redundant systems, remote sense is also provided.
