The basic types are:
- PGW65 wall-mount 65W (0.37W/cm3 – 6.06W/in3)
- PGW100 wall-mount 100W (0.53W/cm3 – 8.72W/in3)
- PGD100 corded 100W (0.48W/cm3 – 7.93W/in3)
- PGD140 corded 140W (0.55W/cm3 – 9.0W/in3)
They “are designed to conform to the Power Delivery protocol and are ideal for industrial and BF-rated medical applications”, claimed the company. “The products are aimed at design engineers working on medical, home healthcare and industrial equipment.”
USB PD 3.1/3.0 and QC4.0/3.0/2.0 fast charging protocols are implemented and outputs are automatically set to 5, 9, 12, 15 or 20Vdc, with PGD140 extending this to 28Vdc.
Input range is 80 to 264Vac and wall-mount types have interchangeable prong assemblies for US, UK, EU, AU or CN mains sockets.
Operation is over 0 to +60°C, with linear derating 100% at 40°C to 50% at 60°C, and no-load input power is <150mW.
They are said to meet Energy Efficiency Level VI (ready for Level VII ) and EU2019/1782.
The body of the largest one is 121 x 66 x 32mm, and weighs ~380g.
Isolation is 2 x MOPP (4kVac) input to output) and 1 x MOPP (1.5kVac) input to ground).
Patient leakage is typically 85µA, with a maximum of 100µA at 264Vac 60Hz.
Approvals include: ANSI/AAMI ES60601-1 and EN60601-1, EN60601-1-11 for medical applications, and UL 62368-1, EN62368-1, IEC62368-1, CAN/CSA C22.2 No. 62368-1-14, CCC, and AU/NZS 62368.1 for IT equipment.
“The units feature Class B conducted and radiated emissions, complying with standards like EN55032/EN55011, which can eliminate the need for a separate EMC/EMI filter,” said XP Power.
The colour and flash-rate of an LED indicates stand-by, normal operation or fault-detected.
Standard protections include over-load and over-voltage with auto-recovery, and short-circuit with trip-and-restart.
Avnet Abacus, Digi-Key, Distrelec, Farnell, Mouser, RS and TME are stocking the PSUs, as is XP Power.
Warranty is three years.
