Introduction
DDRH series is a DIN Rail type DC-DC converter with main features including DIN rail-type easy installation, 57mm
slim width, 10: 1 ultra wide input voltage, -30~+80
℃
wide range operating temperature, DC OK relay contact and
full protective functions...etc.
This series has ultra-high input voltage: 150~1500Vdc and various output options: 5V / 12V /24V / 48V. It 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.
（
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.
（

）
Use wires that can withstand temperatures of at least 90°C, such as UL1015.
