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 is the abbreviation for Limited Power Source.
In the IEC 60950 safety standard, the flame retardant case/enclosure is required for an IT product. When the main circuit of equipment is powered by LPS, it indicates that the voltage, current, and load are below the limits listed in IEC 60950-1 Table 2B; hence, a higher level of flame retardant case/enclosure for reducing the risk is not necessary. In other words, it is allowed to use the case/enclosure that is UL94 HB rated which offers a lower price, features improved physical properties, and meets environmental protection requirements more easily.

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.

MTBF
Mean Time Before Failures (MTBF) calculates the average time between failures of a system/equipment.
 
Lifetime
The lifetime here may also indicate the lifespan of an electrolytic capacitor as the lifetime of a power supply is usually determined by the electrolytic capacitor.
