EN ML30.106 Installation Manual

Product Description

The ML30.106 is a DIN-rail mountable single-phase-input power supply, which provides a floating,
stabilized and galvanically separated SELV/PELV ± dual output voltage with a common return line.

The output of the device fulfils the requirements for a limited power source according to NEC Class

2.

Intended Use

This device is designed for installation in an enclosure and is intended for commercial use, such as
in industrial control, process control, monitoring and measurement equipment or the like. Do not use
this device in equipment where malfunction may cause severe personal injury or threaten human
life.

Installation Instructions

Install device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of the

device. Other mounting orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper

cables that are designed for a minimum operating temperatur e o f 60°C for ambi ent te mperatures up
to +45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temper atur es up to
+70°C. Ensure that all strands of a stranded wire enter the terminal connection.

The device is designed for pollution degree 2 areas in controlled environments. No condensation or
frost is allowed.

The housing of the device provides a degree of protection of IP20. The housing does not provide
protection against spilled liquids.

The isolation of the device is designed to withstand impulse voltages of overvoltage category II
according to IEC 60664-1.

The device is designed as “Class of Protection” I equipment according to IEC 61140. Do not use
without a proper PE (Protective Earth) connection.
The device is suitable to be supplied from TN, TT and IT mains networks. The continuous voltage
between the input terminals and the PE terminal must not exceed 300Vac.

The input can also be powered from batteries or similar DC sources. The continuous voltage
between the supply voltage and the PE/ground potential must not exceed 375Vdc.

A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
The device is designed for altitudes up to 2000m (6560ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 0mm left

and right side. Increase the 0mm to 15mm in case the adjacent device is a heat source.
The device is designed, tested and approved for branch circuits up to 16A (IEC) or 15A (UL) without

additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than
10A B- or 6A C-Characteristic to avoid a nuisance tripping of the circuit breaker.

The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the
same as the ambient or surrounding air temperature and is defined 2cm below the device.

The device is designed to operate in areas between 5% and 95% relative humidity.

Functional Description

The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including inductive and capacitive loads.
The +/– output voltage is generated by one converter. The sum of both voltages is regulated. The
total power of 36W can be drawn asymmetrically or only from one output. It is recommended that
the other output should draw a minimum load of 4% of the total load.

Do not apply return voltages from the load to the output terminals higher than ±20V.
A range selection can be done with the jumper on the output terminal block. An inserted jumper sets

the output voltage to ±15V. An open connection sets the output voltage to ±12V.
The green DC-OK LED reports a voltage on the output terminals above 19V (sum of both output

voltages).
Do not parallel devices for higher output currents.
Do not connect outputs of devices in a series connection for higher output voltages.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 50V (sum of

both output voltages). The output shuts down and automatically attempts to restart.

Technical Data

All values are typical figures specified at 230Vac, 50Hz input
voltage, ±12V 1.5A output load, 25°C ambient temperature and
after a 5 minutes run-in time unless otherwise noted.
