In an attempt to provide stable output and high reliability for different Input Current 4.0A@90V and 264V
applications (communications, networks, servers and work stations),
Portwell conducted a research to provide suitable PSU. In PLUTO series, OUTPUT SPECIFICATION
only high quality components to meet those requirements are chosen. Wattage 250W
The electrical characteristics of the PSU describe the quality of its outputs. Eficiency >=80%
In PLUTO-A2501PJ, all capacitors are from Japanese manufacturers: Holdup Time 17ms, at full load
NCC and RUBYCON. The case material of PLUTO-A2501PJ is SECC Over Voltage Protection +5V:5.5V~6.8V, +12V:13.2V~16.0V,
that comes with high thermal conductive properties which helps to provide +3.3V:3.7V~4.6V
higher heat dissipating capacity. Over Current Protection +5V:20A, +12V:20A, +3.3V:18A
High reliability is also an important feature for PLUTO-A2501PJ. Burn-in
test in 0°C and 50°C for 12 hours at 100% loading is performed. In such EMI & Safety Approval CE, CB, FCC, VCCI, UL, TUV, 80PLUS
test, PLUTO-A2501PJ can meet various environment standards and keep
stable and eficient. DC OUTPUT
For the beneit of valuable machine and data, PLUTP-A2501PJ provides +5V +3.3V +12V -12V +5Vsb
