•
Storage Ambient Temperature Range: -40°C to +70°C
(-40°F to +158°F).
•
Humidity: This converter module is capable of operating
in an ambient relative humidity range of 0 to 90%, non-
condensing.
•
Altitude: The maximum operating ambient temperature
should be derated by 3°C per 1000 feet at an elevation of
6,000 feet.
•
Ventilation Requirements: The converter module is fan
cooled and utilizes front to back forced ventilation.
•
Audible Noise: With a single converter module installed
and operating, the audible noise measured in front of
converter at a 0.6m distance from a horizontal line from
the middle of converter does not exceed 50 dBA with a
temperature of 25°C.
•
Over Voltage Category: II.
•
Power Distribution System: TN/TT/IT.
Note:
The converter module is recommended to be used in an
environment with Pollution of Degree 2 or less. Pollution
Degree 2 applies where there is only non-conductive
pollution that might temporarily become conductive due
to occasional condensation (such as the office
environment).

Standard Features
•
Type of Power Conversion Circuit: High Frequency.
•
Input Voltage Protection:
a.
Fusing: A non-user replaceable fuse is located in the
positive input lead of each DC-DC converter module.
b.
High and Low Input Voltage Inhibit: The converter
shuts down at low or high input voltage.
1.
Low Voltage Disable Point: -40.0 Vdc ±0.5 Vdc;
hysteretic at least 3 Vdc for restart.
2.
High Voltage Disable Point: 59.5 Vdc ±0.5 Vdc;
hysteretic at least 2 Vdc for start.
•
Output Protection:
a.
Overvoltage Protection: When output voltage goes
above a preset value (30.5±0.5V, not to exceed 31V
for more than 150ms), the converter shuts down.
Software settable HVSD level (from controller)
27V-30V.
b.
Power Limit: Output power is limited to 1500W.
c.
Over Temperature Protection: The operation of a
DC-DC converter module will automatically shut
down and lock out if the internal temperature of the
module exceeds a predetermined value. Operation
will automatically resume after the over-
temperature condition is corrected.
•
Series Paralleling Output FET: A series paralleling output
FET is provided in each DC-DC converter module. This
allows the Modules to be paralleled for redundancy.
•
Hot Swappable: The converter module is designed to be
plug-and-play. The converter module can be inserted or
removed from a live DC power system with no damage.
When the converter module is plugged into the system,
the sub-system output voltage will not be affected.
