Introducon
DRA is a DIN rail power supply series featuring adjustable output current. Users are able to set its output current to
a range of 10% - 100% of rated current via 1-10Vdc, PWM signal or resistance. Like other Mean Well s DIN series, ’
they can be mounted on a TS35 Standard DIN rail.
Installaon
( )1 Always allow good venlaon clearances, 5mm le and right, 40mm above and 20mm below, around the unit
in use to prevent it from overheang. Also a 10-15 cm clearance must be kept when the adjacent device is a
heat source.
( )2 The appropriate mounng orientaon for the unit is vercal, the input terminals the bottom and output on at
the top. Mounng orientaons other than that, such as upside down, horizontal, or table-top mounng, is not
allowed.
( )3 Use copper wire only, and recommended wires are shown as below.
Make sure that all strands of each stranded wire enter the terminal connecon and the screw terminals are
securely xed to prevent poor contact. If the power supply possesses mul-output terminals, please make
sure each contact is connected to wires to prevent too much current stress on a single contact.
( )4 Use wires that can withstand temperatures of at least 80°C, such as UL1007.
( )5 Recommended wire strapping length m (0.197 . is 5m ”)
( )6 Recommended screwdriver is 3 , sloed type.mm
( )7 The recommended torque seng for terminals(TB1) is 5 kgf‐cm (4.4 Lb‐in),
terminals(TB2) is 5 5 .8 kgf‐cm ( Lb‐in).
( )8 Each unit requires 0.15mA when dimming funcon is used. Please make sure your controller is capable of
driving the units.
