One of our IT labs consistently trips following a power outage or isolation of the upstream supply by an electrician and won't reset until we've switched most of the sockets that computers are plugged into off. Once reset we can then switch the sockets back on again. The breaker is a Hagar ADN 132 model 30mA RCBO B32. Would I be correct to talk to our estates team about getting this changed for a RCBO with type C breaking characteristics to allow for what I guess to be electrical inrush to the capacitors in the power supplies of the PCs in the IT lab which currently prevents us from resetting the existing breaker. We could just let it be as it is and continue to go to reset it following trips, but I am the only member of the IT team who can reach it without a ladder and it is half way across our campus on the first floor in a stairwell. Let me know what is best to do here

We mainly use Vestel IFM75s here too, any new ones we'll buy will be Vestel at least. Currently we have about 25 on our main site with ~20 more going in in Summer or in the next academic. They are fairly robust, but cannot be beaten on price (from what we've found). Things to consider though. -The IFM series does not have an android host OS (one of the reason's we've chosen it, teachers know they're annotating on the PC as opposed to annotating on the IDP's host OS and not the PC) -When left for a holiday in standby the speakers stop working, a full power cycle at the mains resolves this (We've put them on clearly fused spurs and it is on the teacher's basic troubleshooting guide. There is a rocker on the underside but the fused spur is easier to find) -IR receiver is external (it connects on a 3.5mm TRS connector on the left side and has a foam sticky pad to attach it to the IDP. The status LED is here too. Had 1/20 bad from factory - replaced & shipped free of charge) -They come with a wall bracket in the box - 2 pieces of stamped sheet metal with teardrop cutouts, cast metal studs screw into the VESA holes and a paper wall template -Very configurable, built in volume limiter, RS232/IP(telnet) control -The touch connector is USB micro B, cable is included (Not had any problems, but could have trouble if regularly disconnected or strained)
