Output Protection
External Voltage: Output will withstand forward voltages of up to 140V (O/P 1), 70V (O/P 2)
or 20V (O/P 3). Reverse protection by diode clamp, 3A max..
Fault Trip: The output will be shut down if a trip conditions listed below occurs.
OVP or OCP Exceeding over-voltage or over-current settings for the output.
Over Temperature: Monitors internal temperature rise to protect against excess ambient
temperature or blocked ventilation slots.
Connection
Output Terminals: Universal 4mm safety binding posts on 19mm (0·75”) spacing at front.
Screw terminals at rear (MX180TP only).
Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires.

either simultaneously (default) or with timed delays from 10ms and 20s.
Delayed operation indicated by flashing key illumination.
VOLTAGE TRACKING
The power supply can be set so that the voltage of output two is automatically set equal to that of
output one and tracks any changes. The outputs remain isolated.

Ethernet (LAN)
Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to Local
Area Network or direct connection to a single PC.
LXI Compliance
LAN interface is compliant with LXI Core 2011. (LXI is the abbreviation for Lan eXtensions for
Instrumentation). For more information visit: www.aimtti.com/go/lxi
