This article provides specifications for Elo P/N: E695712, 120W Power Adapter.

Electrical Characteristics

Input Characteristics

Rated Voltage

• Rated input voltage: 100 Vac – 240 Vac.

Input Voltage Range

• The adapter shall operate from 90 Vac to 264 Vac.

Rated Frequency

• Rated frequency: 50 Hz – 60 Hz.

Input Frequency

• Input frequency: 47 Hz – 63 Hz.

Input Current

• <2.0 A rms at 100 Vac input and maximum load.

Inrush Current

• Maximum inrush current shall be less than 150 A at 264 Vac input and must not cause any damage to the adapter.

Power Efficiency

• Minimum efficiency of 88% measured at both 115 Vac and 230 Vac input voltage, across load conditions of 25%, 50%, 75%, and 100%, including DC cable loss.

Standby Power

• Maximum standby power of less than 0.21 W at both 115 Vac and 230 Vac input.

Output Characteristics

Rated Output Voltage

• The rated output voltage is specified at 24.0 VDC.

Voltage Output Range

• The output voltage will range from 22.8 VDC to 25.2 VDC when the load is applied.

Rated Power

• This adapter supports a continuous output of 120 Watts under all specified conditions.

Rated Current

• This adapter can operate from 0 A to 5 A, with the output voltage within the specified range in section Voltage Output Range.

Output Ripple and Noise (Input AC Voltage: 100 V –240 V)

• Output ripple voltage is limited to 240 mV peak-to-peak or less.
• Output noise voltage is also limited to 240 mV peak-to-peak or less.

Measured Methods:

• T1: Performed using a 20 MHz bandwidth oscilloscope.
• T2: Applied a 0.1 µF ceramic capacitor and a 10 µF electrolytic capacitor across output connector terminals.
• T3: Measurements taken at the end of the DC cable.

Stability

The adapter operates unconditionally stable within its normal operating specifications.

Protection

Short Circuit Protection

• The adapter protects against short circuits between output terminals without resulting in fire hazards or damage, resuming normal operation once the short is removed.

Over Current Protection

• When over-current occurs (120% < OCP <180%), input power reduces or ceases output without causing damage, with automatic recovery upon removal of over-current condition.

Peak Load

• While operating with an input of 100–220 Vac, the output voltage remains within 18–26 V, with specific peak loads defined as follows:
• 8 A peak for a duration of 2 ms (duty cycle approximately 14, assuming 2 A RMS), rise/fall rate: 2 .5 A/µs.
• 20 A peak for a duration of 100 µs (duty cycle approximately 40, assuming 2 A RMS), rise/fall rate: 2 .5 A/µs.

Connector Dimensions: 

• DC barrel plug 2.5mm (+/- 0.1mm) pin ID, 5.5mm (+/- 0.05mm) barrel OD, 8.0mm (+/- 0.3mm) Barrel length) | Center Pin Positive
