	Item # LPSA10, Level Probe Surge Arresters

The Level Probe Surge Arrester provides transient surge protection for the control inputs of any of MPE's pump control devices that have conductance probe inputs for level measurement.

The unit has ten channels and may be used with any of MPE's ten electrode conductance probes (Level Probes), but can also be used with single electrode, or three electrode probes.

Each channel has an MOV (Metal-Oxide Varistor) that is capable of shunting large transient currents to ground (up to 1000 Amps).

Following each MOV is a TVS (Transient Voltage Suppressor Diode) capable of limiting the voltage going to the controls inputs from going beyond ± 26V.

Between each MOV and TVS is a 100 Ω, 5 Watt wire wound resistor that protects the TVS from excessive voltages and currents not stopped by the MOV.

The grounding terminal on the LPSA10 must be connected to the control panel ground by a 12 AWG.
