RHB40 Regulated DC to DC Boost Converter | 8 to 30.5 VDC, 400 W

Product Description
The RHB40 is primarily designed for 28 VDC buss systems to deliver regulated 24 VDC power. The RHB40 will operate from an input voltage range of 12–24 VDC (down to 8V DC in abnormal mode) with continuous output current up to 16.6 Amps and 190% overload current capability (31.5 Amps).
The RHB40 is designed to maintain on-line critical equipment and instruments during engine starts. For an input voltage greater than 24 VDC the unit operates in a conduction or override mode and delivers up to 35 Amp of continuous output current.
Specifications
Weight:
4.4 lbs (2 kg)
Dimensions:
4.00 x 4.20 x 8.25 in (101.6 x 106.6 x 209.5 mm)
Input Voltage:
Normal Voltage: 12 to 24 VDC (for regulated output) Extended Range: 8 to 30.5 VDC
Current:
31 A typical at 14 VDC input voltage & at full load 37 A typical at 12 VDC input voltage & at full load 0.5 A maximum at no load
Overload:
70 A for 15 Sec, 140 A for 2 Sec, 210 A for 1 Sec, or until a 35 A input circuit beaker trips
Operation:
Two modes: Switching (or Regulation) and Override (or Conduction)
Output Voltage:
24 VDC regulated for input voltage from 12 to 24 VDC Greater than 22 VDC, 633 watts for input voltage of 8 VDC Follows input voltage for the input above 24 VDC (Override Mode)
Current:
16.6 A (continuous), 31.5 A (for one minute)
Power:
400 Watts continuous for input voltage from 12 to 24 VDC 633 Watts for 20 seconds at VDC input voltage 750 Watts for 1 minutes at 12 VDC or higher input voltage
Regulation:
3% for load, 2% for line and 3% for temperature
Protection (OL):
Withstands, without damage or degradation, loads exceeding 100% of rated current. Output collapses to input when load exceeds approximately 190% (31.5 A). Unit delivers rated output upon removal of the overload (OL) condition.
Short Circuit:
(SC) Protection: Unit is protected against output short circuit by an external 35 A circuit breaker per MIL-C-5809.
Thermal (OL):
(TO) Protection: Unit is protected against a prolonged thermal overload condition by reverting the operating mode from switching (or regulation) to override (or conduction) mode.
Efficiency:
92% (typical) at 14 VDC input
Temperature:
-45°C to 70°C (Bottom plate temperature not to exceed 75°C)
Altitude:
55,000 ft
Environmental:
Designed to meet FAA TSO-C71 & Do-160C/D by design similarity/analysis F2-BBB(LV)EWXDFSZZAZZYZKXAA
Compliance:
FAA TSO-C71
Finish:
Gold iridite per MIL-C-5541, Class 1A
