DC Input:
DC Input range: 18 to 48 VDC,
per MIL-STD-704E
No damage for:
MIL-STD-1275A (100V for 50mSec)
MIL-STD-704A (80V for 0.1Sec)

DC Output:
Output range – 1.5 to 28V
Output current – max 40A

Isolation
200V between Input and Output
200V between Input and Case
100V between Output and Case

Line/Load regulation:
Less than 1%
(no load to full load, –55°C to +85°C)

Efficiency :
Typical 90-92%
(full load, room temperature)

EMI/RFI:
Design to meet or exceed
MIL-STD-461C:CE03, CE07, CS01, CS02,
CS06, RE02, RS02, RS03

Ripple and Noise:
Less than 50mVp-p, typical (max. 1%)
without external capacitance.
When connected to system capacitance
ripple drops significantly

Load Transient Overshoot and
Undershoot
Output resistance at load change of 50%100% is 30-200mOhm (depending on output
voltage). Output back to steady stated within
300-500µSec

Turn on Transient
Voltage overshoot at during power on is
less than 3% nominal voltage

Output
• Electronic over voltage protection –
Internal control protects unit (no damage)
10% above nominal voltage
• Passive tranzorb on outputs –
20% above nominal voltage
• Current limiting – Continuous protection
(10-30% above maximum current) for
unlimited time (Hiccup)

General
• Over temperature protection:
Shutdown at base plate temperature of
+105°C (±5°C) Automatic recovery at
base plate temperature lower than
+95°C (±5°C)

Electrical Specifications

Protections*
Input
• Inrush Current Limiter –
peak value of 5 x Iin for less than 50µSec
• Under voltage protection –
unit protects itself (no damage) below
16.5Vdc
• Over voltage protection –
unit protects itself (no damage) above
52Vdc

* Thresholds and protections can be modified / removed – please consult factory.
