Introduction
DDRH series is a DIN Rail type DC-DC converter with main features including DIN rail-type easy installation , ultra
wide input voltage, wide range operating temperature, DC OK relay contact and full protective functions...etc.
DDRH-15/30/45/60 series has ultra-high input voltage: 150~1500Vdc and various output options: 5V / 12V /24V /
48V. DDRH-120/240 series has ultra-high input voltage: 250~1500Vdc and various output options: 12V / 24V /32V /
48V.DDRH series is suitable for industrial automation, surveillance, telecommunication and can be widely deployed
in the applications of new energy generation such as solar power, and windmill power generation, for instances,
photovoltaic power systems, high voltage inverting and so forth.
Installation
（1）Always allow good ventilation clearances, 5mm left and right, 40mm above and 20mm below, around the unit
in use to prevent it from overheating. Also a 10-15 cm clearance must be kept when the adjacent device is a
heat source.
（2）The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on
the top. Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not
allowed.

Note
：
Current each wire carries should be de-rated to 80% of the current suggested above when
using 4-6 wires connected to the unit.
Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are
securely fixed to prevent poor contact. If the power supply possesses multi-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 90°C, such as UL1015.
（5）Recommended wire strapping length is 6mm (0.236”).
（6）Recommended screwdriver is 3mm, slotted type.
（7）The recommended torque setting for terminals is shown as below.

（9）Mounting Instruction：
Mount as shown in figure only, with input terminals down, or else sufficient cooling will not be possible.
Admissible DIN rail：TS35/7.5 or TS35/15
For rail fastening：
（a）Tilt the unit slightly rearwards.
（b）Fit the unit over top hat rail.
（c）Slide it downward until it hits the stop.
（d）Press against the bottom for locking.
（e）Shake the unit slightly to check the locking action.
（10）Installation clearancs : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended
when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is
recommended.
（11）The ambient temperature derating of 3.5°C/1000m with fan less models and of 5°C/1000m with fan models
for operating altitude higher than 2000m(6500fit).

“CAUTION：FOR USE IN A CONTROLLED ENVIRONMENT. REFER TO MANUAL FOR ENVIRONMENTAL CONDITION”
ATTENTION: A UTILISER DANS UN ENVIRONNEMENT CONTROLE. REFEREZ VOUS AU MANUEL POUR
LES CONDITIONS D’ENVIRONNEMENT.
（1）Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Please do
not remove the case of the power supply by yourself!
（2）Risk of electric arcs and electric shock (danger to life). Connecting both the primary and the secondary sides
together is not allowed.
（3）Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection!
（4）Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
（5）Only install the unit in a pollution degree 2 environment (Note.1).
（6）Please do not install the unit in places with high moisture or near the water.
（7）The maximum operating temperature is 80°C for the DDRH-60, please do not install the unit in places with
high ambient temperature or near fire source.
（8）Output current and output wattage must not exceed the rated value on its specification.
（9）Disconnect system from supply voltage:
Before commencing any installation, maintenance or modification work: Disconnect your system from
supply voltage. Make sure that inadvertent connection in circuit will be impossible!
Note.1: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become
conductive due to occasional condensation. Generally refer to dry, well-ventilated locations, such as
control cabinets.
