EA-AC

About the EA-AC

EA-AC is an AC/DC power adapter that is manufactured by Automation Direct for the C-more EA7 series. The power supply cable torque is 71-85 ox-in. The power connector mounting torque is 71-85 oz-in. The mounting flange screw torque is 57-71 oz-in. This AC/DC adapter is used for C-more EA7 and EA9 series touch panels. The input power is 100-240 VAC, and the frequency of the input power source is 50/60 Hz. This adapter provides 24 VDC at 1.5 A. Power fault features help protect data being logged to a Compact Flash or SD card during power failures. For proper operation, C-more EA7 series panels must have firmware version 1.21 Build 6.18 E or higher. The permissible momentary power failure is within 40 ms. The input power is 68 VA or less. The noise immunity is 1000 VAC p-p with a proper ground connection on an AC terminal block. The hi-pot is 1000 VAC for one minute with a proper ground connection on an AC terminal block. The vibration resistance is compliant with IEC61131-2. The shock resistance has a sine half wave pulse shape and a peak acceleration of 147 m/s2 (15 G) in 3 directions (X, Y, Z), 2 times each. The thermal protection is 140°C with autorecovery. The short circuit protection is 2.6 A at 85 VAC, 2.8 A at 100 VAC, and 3.9 A at 264 VAC. The static electricity discharge resistance is compliant with IEC61000-4-2m wherein the contact is 4 kV. This power adapter is UL508 approved and is for use in a pollution degree 2 environment. The cooling method is natural convection. The dimensions are 3.00” (H) x 3.66” (W) x 1.42” (D).
