DC – AC INVERTER FOR RAILWAY APPLICATIONS
• NOMINAL 36 VDC INPUT (STANDARD LRV POWER BUS)
• 2 TO 1 SURGE CAPACITY
•2000 VDC ISOLATION
• WIDE TEMPERATURE RANGE
• RUGGED CONSTRUCTION
25-49.6 VDC. The nominal volt age is 36 VDC.
EFFICIENCY:
70% minimum or greater .
LINE REGULATION:
The unit maint ains the output voltage
between 105 V AC and 122 V AC for nominal and full range
of input voltage range.
LOAD REGULATION:
± 1% for change from no load to full
load.
OUTPUT VOLTAGE :
115 VAC nominal, 60 Hz.
OUTPUT CURRENT :
150 V olt-Amperes, with a two-second
surge cap acity of 300 Volt-Amperes.
OPERATING TEMPERATURE RANGE:
Operating: -20 o C (-4 o F)to +50 o C (+122 o F).
Non-Operating: -20 oC (-4 o F) to +60 o C (+140 o F).
ISOLATION:
The isolation between input and output, and
between input and chassis is capable of passing 2000 V
stress test.
20 Megohms or greater between input and chassis, input and output, and output and
chassis when measured at 50 VDC.
SHORT CIRCUIT PROTECTION:
The unit provides protection against overloads and short-circuits. No damage
results from any overload condition. The unit automatically
returns to full rated operation within three seconds upon
removal of the overload condition.
OVER VOLTAGE PROTECTION:
The unit is protected electronically from an overvoltage condition. Input power to the
unit needs to be removed and re-applied to resume unit
operation.
VOLTAGE POLARITY :
Accidental reversal of the input voltage polarity does not damage the unit when the unit is
protected by a 20-Ampere fuse or circuit breaker at the power
source.
WEIGHT:
25 lbs max.
