TSO'd REGULATED DC TO DC POWER CONVERTER

10-24Vdc to 24Vdc Regulated DC Power Converter

The RR18, converts a wide input voltage range of 10-24 Vdc to a dual regulated 24 Vdc outputs. The converter is capable of delivering 160 Watts and 25 watts continuously for an input voltage range of 10 to 24 Vdc. The converter delivers at full load a minimum voltage of 18 Vdc at 8 Vdc input voltage.

Control circuitry includes use of a popular PWM for voltage regulation and output current limit. Protection circuitry includes the output over-voltage limit.

Specifications:

Input Voltage:

 

Normal Voltage:

10 Vdc to 24 Vdc (for regulated output).

Abnormal Range:

8 Vdc to 35 Vdc.

Current:

CH1

12.6 Amps typical at 14 Vdc input voltage & at full load. 19 Amps maximum at 10 Vdc input voltage & at full load. 0.05 Amps maximum at no load.

 

CH2

1.9 Amps typical at 14 Vdc input voltage & at full load. 3.0 Amps maximum at 10 Vdc input voltage & at full load. 0.05 Amps maximum at no load.

Output Voltage:

CH1 & 2

24 Vdc regulated (for input voltage from 10 to 24 Vdc) Greater than 18 Vdc for input voltage of 8 Vdc. Follows the input voltage for input above 24 Vdc.

Power:

CH1

160 Watts continuous for Ein > 10 Vdc.

 

CH2

25 Watts continuous for Ein > 10 Vdc. 185 watts total continuous power (not to exceed)

Current:

CH1

6.67 Amps Continuous (full load)

 

CH2

1.04 Amps Continuous (full load)

Regulation:

CH1 & 2

2% for load, 1% for line(10-24 Vdc) and 2% for temperature.

Protection (OL):

Withstands, without damage or degradation, loads exceeding 100% full load. Output collapses to input when load exceeds approximately 190% of full load current. Unit delivers rated output upon removal of the overload (OL) condition.

Short Circuit  (SC) Protection

Unit is protected against output short circuit by the tripping of external input circuit breakers.
