Instruction of Minimum Energy
No-load Controller
(MEC)
Ⅰ.General
Description：
Minimum Energy
no-load Controller (MEC) is a controller for
external power supplies (Linear Adaptors) to
meet Maximum Power in No-Load bellowing 0.2W,
which exceed in the requirements of US “ENERGY
STAR”, Australia (MEPS), China (CECP)
standards.

Working Range with
Adaptors:
1. Adaptor Input
Voltage:
110
VAC±20% @45Hz~65Hz (USE FOR
TYPE ME11)
220 VAC±20% @45Hz~65Hz (USE FOR
TYPE ME22)2. Adaptor Output
Current: 0.5A~20A3. Maximum Power in
No-Load: ≤0.2W4. Adaptors
Power：3~250W
5.
Physical Dimensions: cuboids,
23.0×12.4×13.1(mm3)6.Operating temperature range:
-20℃~85℃7. High
voltage test: ME11 type: from primary-side to
secondary-side electrical strength is 1.75KV,
1Min, ≤1mA ME22 type: from
primary-side to secondary-side electrical
strength is 3.75KV, 1Min, ≤1mA8.
Short circuit and open circuit protection:
accords with UL1577 standards
9.
Start-up Current of the
secondary-side：IO′≥25%IOmax
(IOmax is the maximum of
secondary output current, IO′is the
start-up current of the
secondary-side).
Note:1.
Primary coil is that the MEC connects to the
primary circuit of the transformer, with “I”
marker in the device package. Secondary is that
the MEC connects to the secondary circuit of the
transformer, with “II” marker in the device
package.
2.
Secondary minimum start-up current
IO′is that in the condition of
controlled in holding state, the current of
secondary connected with load
IO′=UO/RL≥25%IOmax,
for example, when the maximum output current is
IOmax=1A, the secondary minimum
start-up current IO′is
250mA.
Ⅲ.
Application
1. working power
supply adaptor; (such as chargers, mp3,
radiophone power supply, lighting of machine
tool, safelight, radio, stirrer, drinking water
dispensers and so on)
2. mechanic
electric meter;
3. energy saving
socket;
4. appliance
production;
5. other
productions which need AC power supply and low
standby power
IV Physical
Dimensions
Note: Where
marks “I”is the primary, the distance of the
primary pins is 8mm. Where marks
“II”is the secondary, the distance of the
secondary pins is 8mm.
V.
Mode of
Connection：
The using method is simple. It does not
change the original production craft of the
working power supply. It just simply series the
module into the primary and secondary
circuit The mode
of the connection:
1、DC Output
Adaptors
2. AC Output
Adaptors:
Note: 1.
Schottky diodes are commended in DC output
adapter to achieve Energy Star standards
of the average energy efficiency
requirements
2. The two pins
of the primary-side can be exchanged, and in the
secondary-side the two pins can be exchanged
too, but please pay attention that primary and
secondary can not be in reverse.

ME11 Input
of Adaptors：110 VAC±20% /45Hz
～65Hz；
ME22
Input of Adaptors：220 VAC±20% /45Hz

For example, ME22
2-50 means that the input voltage is 220VAC/
45Hz ～65Hz, the output current is within 2A and
the power is 50W.
