SN Series (SN180D)
180 Watt Dual Output Power Supply
28 Vdc to AC Sine Wave Inverter

Specifications
Input:	24 - 30 Vdc, single phase.  (see option H).
Output:	25.4 - 28.6 Vac, 108-122 Vac
Efficiency:	50% typical at 27 Vdc input and full resistive load (no options).
Line Regulation:	Within 0.5% for full input change 24 Vdc to 30 Vdc with load constant.
Load Regulation:	Within 1.0% for load change of one half to full load with line constant.
Wave Form:	Sinusoidal with a 4% maximum harmonic distortion into a resistive load.
Frequency Stability:	±1% drift with time (within the first 8 hours after 30 seconds warm-up).
Frequency Accuracy:	±0.5% is initial setting tolerance.
Load Power Factor:	Derate linearly from 100% rated power at unity to 70% rated power at 0.7 power factor lagging or leading.
Isolation Voltage:	750 Vdc, input to output; 200 Vdc, input to case; 750 Vdc, output to case.
Insulation Resistance:	50 Mohms between input and output, input and case, output and case, when measured at 50 Vdc.
Temperature Range:	Operating: -55°C to +100°C maximum, at center of the baseplate. Storage: -65°C to +125°C, ambient.
Temperature Coefficient:	0.06% / °C  from -55°C to +100°C, voltage change, frequency change, 1% maximum.
Input Transient Protection:	Unit will withstand 80 Vdc for 0.1 second, in accordance with MIL-STD-704A.
Load Transient Response:	Output voltage returns to regulation limits within 5 cycles for a load change of no load to full load.
Load Transient Overshoot:	10% maximum from nominal voltage set point.
Short Circuit Protection:	Completely protected against a short circuit of any duration. Unit must be recycled to restore output to normal when overload is removed.
EMI:	Units were designed and built to minimize EMI/EMC emissions, and comply with the requirements of MIL-STD-461A by virtue of their topology, construction and enclosure.
Reliability:	MTBF is calculated per MIL-HDBK-217D at 50°C baseplate temperature with maximum operating input voltage and maximum rated output power. The MTBF at ground benign environment is 156,366 hours and 15,722 hours for air inhabited transport environments. With -ER option MTBF at ground benign is 907,070 hours and 93,030 for air inhabited transport environments. Consult factory for other model and environment information.
Environment:	Encapsulated and hermetically sealed to meet the environmental requirements of MIL-STD-810C.
Connectors:	Standard unit is provided with an input solder 4 pin header. (See option -A for other connectors.)
Weight (Lbs.):	Maximum 5.5 lbs. not including options.
Size (inches):	AxBxC
	6.0 x 6.0 x 2.50
