There are several factors that will influence the test result of the power efficiency including the test instrument, test fixture, input/output cable, specification of the plug, whether the condition of the power supply is stable, etc.

Power supplies do not have the applied parts that can be directly used by the patients; hence, they can not be classified on the basis of medical device classification. The power supply is classifiable only when it is paired with the end device or system. The way to figure if the power supply is appropriate to your medical device or system is to check if the end device or system has any special requirement for the power.

Class I: Using basic insulation between primary and secondary against an electrical shock from dangerous voltage.
Class II: Using double insulation or reinforced insulation between primary and secondary against an electrical shock from dangerous voltage.

Regarding IT certificated products:

S series
Warranty: 3 years
Operating Temperature: 100% load at 0°C~+40°C and 0°C~+50°C (can be launched at -20°C)

I series
Warranty: 3 years
Operating Temperature: 100% load at -20°C~+40°C and -20°C~+50°C

E series
Warranty: 1 year
Operating Temperature: 100% load at 0°C~+40°C

Sinpro's medical power supply can apply for Type B (Body) or Type BF (Body Floating) classification when it is paired with the device or system. As Type CF (Cardiac Floating) has a higher criterion on leakage current, the customization or reevaluation of the power supply is required.

M series
Warranty: 5 years
Operating Temperature: 100% load at -40°C(can be lunched)~+50°C

H series
Warranty: 3 years 
Operating Temperature: 100% load at -20°C(can be lunched)~+40°C and -10°C(can be lunched)~+40°C

Sinpro has no particular overseas agents, but there are many Sinpro's distributors/dealers around the world.

As long as the products comply with the standards of Medical Devices Directive (MDD), Low Voltage Directive (LVD), Electromagnetic Compatibility (EMC), Energy-related Products (ErP), and with CE marking, the products can be sold in Europe.

Since the standards of IEC/EN/UL 60950 are different from IEC/EN/UL 62368, the evaluation items between 60950 and 62368 would not be the same.

LPS (Limited Power Source) has long been the go-to way to relax fire-enclosure requirements and cut material costs in power supply design. But with IEC 60950-1 retired and IEC 62368-1 now the governing standard, the mechanics behind that benefit have shifted. This article walks through what LPS originally meant, and maps it onto today's PS1/PS2/PS3 power-source classification including where LPS/PS1 and SELV/ES1 look interchangeable but aren't quite.

MOOP (Means Of Operator Protection): An insulation protection for operators.
MOPP (Means Of Patient Protection): An insulation protection for patients.

Sinpro's standard power supplies can charge most laptops, tablets, and devices that are with BMS (Battery Management System) once it is supplied with stable power. When choosing a power supply, it is necessary to consider if it can supply extra power to the circuit that generates an additional consumption when in operation.
