TECHNICAL INFORMATION
RATED PRIMARY VOLTAGE (V)
This is the supply voltage assigned to the transformer by the manufacturer.
RATED SECONDARY VOLTAGE (V)
This is the secondary output voltage assigned to the transformer when supplied with the rated primary voltage, frequency range, rated secondary
current, all assigned by the manufacturer for the specified operating conditions of the transformer.
RATED POWER (VA)
The specified power levels in this catalogue are the secondary power levels, in other words, those available when the transformer is loaded. It is the
product of the RMS rated secondary voltage by the RMS rated current. If the transformer has more than one output winding, the rated power
denotes the maximum sum of the products of RMS rated secondary voltage by the RMS rated secondary current, respectively. This rated power is
defined for rated ambient temperature conditions.
example : P = 3,2 VA ta 70/B
The transformer can deliver 3.2VA at maximum ambient (70°C), the load consisting of a resistor load defined by R(load) = U(sec)2/P (assigned U sec &
P values), heating does not exceed the relevant limit for Class B components used in this construction.
NOTE : When the transformer is intended to supply DC voltage and current in conjunction with rectifiers and smoothing capacitors, the VA power
required from the transformer is far higher than the U(DC) and I(DC) product. To help you to determine the true transformer power, our Technical
Department is at your disposal.
AMBIENT TEMPERATURE (ta)
The maximum temperature at which the transformer may be operated continuously under nominal conditions of use. It is the air temperature measu-
red close to the transformer after thermal stabilization when operating at rated conditions.
HEATING
The increase of the winding temperature when operating at rated conditions and maximum ambient temperature. The heating must be determined by
the resistance method.
TEMPERATURE CLASS
The international classification of temperature classes is as follows :
It defines the maximum temperature the transformer components must withstand in continuous operation, in compliance with the N° 85 IEC publica-
tion classification. There insulating materials are therefore certificated for the thermal index corresponding to the declared class in accordance with
N° 216 IEC standard.
PARTICULAR POINTS OF EN 61558-2-6 STANDARD FOR SAFETY TRANSFORMERS
On-load secondary voltage tolerance.
This should not differ from the rated value by more than :
10% for transformers with build-in resistance to short-circuits (a supplement of 5% is granted on the 2 nd secondary for tranformers with 2
secondaries).
5% for other transformers whatever the secondaries number.
Off-load secondary voltage.
The values given in this catalogue are maximum theoretical values.
NOTE : For safety transformers, this should never exceed 50 V rms. In the case of a transformer with several secondaries, the sum of the
secondary voltages should be less tan 50 V rms.
ADAPTED TRANSFORMERS FROM THE STANDARDS SERIES
Any transformer whose requires Power and Ambient corresponding to those of our 44000 & 45000 range, and whose secondary voltage can fit in our
minimum to maximum secondary range will be covered by EN61558-2-6,EN60950, or UL506 approvals, depending on the effective choice .
SPECIAL TRANFORMERS
MYRRA can use the 44000, 45000 or 46000 standard ranges to examine any transformer for compliance with your specifications and with internatio-
nal standards.
On request, we can add thermal protection, thermal fuse, thermal switch-CTP.
In certain cases, the addition of thermal protection enables the ambient temperature to be increased, while still complying with EN 61558.

• For boxes with 2 lugs and pin type output, add suffix 1 to the reference of the standard transformer (example : 44198-1)
• For boxes with 2 lugs and 2,8 «faston» output, add suffix 2 to the reference of the standard transformer (example : 44199-2)
• For boxes with 4 lugs and pin type output, add suffix 3 to the reference of the standard transformer (example : 44200-3)
• For boxes with 4 lugs and 2,8 «faston» output, add suffix 4 to the reference of the standard transformer (example : 44201-4)
These models are not available on stock.
Series 44000 transformers can be
equiped with boxes with lugs and also
2,8 «faston» terminal tags while still
conforming to the specifications in
the standard references.

47000 SERIES
ELECTRONIC TRANSFORMERS
76
47000 SERIES - ELECTRONIC TRANSFORMERS
MYRRA encapsulated electronic transformers are
Switched Mode Power Supplies based on Flyback
topology.
They constitute an interesting alternative to the
traditional supply in the most common applications of
power lower than 5W.
ENERGY SAVING due to high efficiency and low standby
power
The applications for the Electronic serie are :
• Alternative to the linear transformers in all
AC/DC applications of power up to than 5W
• Alternative to DC/DC converters for application
in D.C.current (Telecom supplies, electric
substations etc.)
• Industrial, domestic and consumer electronics
applications
• Standby devices and others DC or AC auxiliary
supplies
With the same footprint as a EI30 transformer, they will
replace:
- 50 Hz Transformer
- Fuse
- Bridge Rectifier
- Filtering Capacitor
Regulated types will also replace linear regulator and
heatsink
MAIN FEATURES
• Wide input voltage range
• Increased power. 3 x compared to standard
EI30 transformer
• Better energetic efficiency : 70% typical com-
pared to 40% for the conventional supply
• Very low Standby Power consumption: meets
requirements of Energy Star or EC Code of
Conduct
• Same footprint as EI30 transformer : Upgrade
your application without redesign of PCB
SAFETY STANDARDS
Meets all requirements of:
• EN 60950
• EN 60335
• EN 61558-2-17
• Uses UL listed components
• Uses UL 94-V0 plastic and resin
EMC STANDARDS
Conducted and radiated emissions conform to
• EN 55014-1
• EN 55022 class B
