Model and configuration

Full ordering code GEM40I05-P1J
Series and product GEM40I single-output medical AC/DC adapter with interchangeable AC plugs.
Code meaning GEM: medical adapter series; 40: nominal family class; I: interchangeable AC plug; 05: 5 V output; P1J: standard centre-positive tuning-fork DC plug.
Safety model GEM40I05
Supply configuration P1J DC output lead is the standard configuration. The interchangeable AC plug kit is sold separately.

Output specifications

DC output voltage 5 V
Rated current / current range 5 A rated; 0 to 5 A range.
Catalogue-rated maximum power 25 W. Select the load within both the rated current and rated power limits.
Ripple and noise, maximum 100 mVp-p
Voltage tolerance ±5.0%
Line / load regulation ±1.0% / ±5.0%
Typical efficiency 84%
No-load consumption / efficiency level <0.1 W; Level VI. EISA 2007 / DoE and EU ErP.

Input and start-up

Input range / frequency 80–264 VAC or 113–370 VDC; 47–63 Hz.
AC input current 1 A at 115 VAC; 0.6 A at 230 VAC.
Maximum inrush current 30 A at 115 VAC; 65 A at 230 VAC.
Set-up / rise / hold-up time 500 / 30 / 16 ms at full load, at both 115 VAC and 230 VAC.
Input class Class II, without an earth pin.
Touch current <100 µA at 264 VAC.

Protection

Short circuit and overload Short-circuit protection is listed. Overload: 105–160% of rated output power; hiccup mode recovers automatically after the fault is removed.
Overvoltage 110–140% of rated output voltage; zener-diode clamping with the output-short protection mode stated in the datasheet.

Temperature and input derating

Working ambient range -25 to +70°C, subject to the load curve.
Thermal curve 100% load from -25 to +40°C; reduce along the plotted line to 50% at +70°C.
Low-input-voltage curve 80% load at 80 VAC, increasing to 100% at 115 VAC; 100% from 115 to 264 VAC.
Working humidity 20–90% RH, non-condensing.
Storage -25 to +85°C; 10–95% RH.
Temperature coefficient ±0.03%/°C from 0 to 40°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes each along X, Y and Z.

Apply both temperature and input-voltage derating when selecting the permitted load. The wider working range does not mean full-load operation at every temperature.

Medical safety and system integration

Isolation / patient environment 2 × MOPP between primary and secondary. Suitable for BF applications with appropriate system consideration.
Safety approvals in this catalogue ANSI/AAMI ES60601-1 / 60601-1-11 and TUV EN60601-1 / 60601-1-11 approved.
Input-to-output withstand 5656 VDC.
Insulation resistance Input to output: 100 MΩ at 500 VDC, 25°C and 70% RH.

EMC immunity EN61000-4-2,3,4,5,6,8,11; light-industry level, criteria A.

The adapter's medical isolation and BF suitability must be assessed within the complete equipment. The finished system must be checked again for EMC compliance.

Typical applications listed for this family include blood-glucose and blood-pressure meters, nebulizers, inhalers, portable medical devices and sleep-apnea devices.

Dimensions, DC connection and installation

Body dimensions 75.5 × 39.1 × 56.2 mm (L × W × H).
