Introduction: 
- Introduce the industrial graded SS-2U50ES Series Power Supply.
- Design to fit perfectly into your 2U Rackmount chassis.
- Triple circuit protections and Active PFC. SS-2U50ES offer unswerving performance for your 2U chassis.

* AC Input Voltage Range: 100VAC ～ 240VAC, +/-10%, 47 to 63 Hz.
* INPUT CURRENT:8.0 A ( RMS ) FOR 115VAC /4.0 A ( RMS ) FOR 230VAC.
* Input Power Factor: The minimum power factor at full load shall be 
   0.98/115V 60 Hz and 0.95/230V 50 Hz.
* Inrush current: 35A MAX. FOR 115 VAC / 55A MAX. FOR 230 VAC.
* DC Output: 500W maximum

1. Noise Test - Noise bandwidth is from DC to 20 MHz.
2. Ripple frequencies greater than 1MHz shall be attenuated by the measurement System.
3. Add 0.1uF/10uF capacitor at output connector terminals for ripple and noise measurements.
4. The combined total power from 5V & 3.3V shall not exceed 170W.

• DIMENSION: D200 X W100 X H70mm 
• COOLING: ONE 60mm DC FANS.
• TEMPERATURE RANGE: Operation 0℃~45℃
• HOLD UP TIME: 16ms at maximum load & normal input voltage
• EFFICIENCY: TYPICAL >80% AT 115VAC, FULL LOAD.
• POWER GOOD SIGNAL: PW-OK is power good signal and should be asserted high by the Power Supply to indicate that +5VDC and +3.3VDC output are above the under voltage thresholds of the Power Supply TTL. compatible signal out with 100ms to 500ms.
• OVER POWER PROTECTION: The Power Supply shall shut down when output power exceeds 110﹪to 160﹪ of full load and require a power on cycle be performed by the operate
• OVER VOLTAGE PROTECTION: Standard on +5.0V, set at 6.5VDC ?0.75VDC
• SHORT CIRCUIT PROTECTION: A short circuit placed between the DC return and the output shall cause no damage and the Power Supply shall shutdown.
• EMI: FCC CLASS B, CISPR22 CLASS B.
• AGENCY APPROVALS: TO MEET UL, CUL, TUV.
• MTBF OF Power Supply ELECTRONNIS: 100,000 hours at 25℃ 75% loading.
