3 Channels Trigger Level Unit: PH203-008-03

3 Channels Trigger Level Unit combines lightning current and magnetic field analysis units and controls each trigger level respectively.
Voltage is checked with a circuit tester and trigger level set accordingly.
Although the setting voltage is (+), it generates (-) voltage inside and window comparator generates the trigger signal.
Input signal is released straight from output connector.

Input impedance 10 k ohm
Input/output rating voltage } 2V
Setting level 0V`0.8V (volume setting)
Monitor output Setting level
Trigger output Open collector
3channels OR
Comparator method Window comparator
Signal input connector BNC
Trigger output connector BNC
Power supply AC100V-50/60Hz
Consumption electricity 0.1W
Frequency 1Hz to 5MHz
Operating temperature limit 0 to 40

Dimension 88(H) x 320(W) x 330(D) mm
Weight 0.5kg

Direct lightning measurement with camera or VCR System. Rogowski Coil. optical-electronic converter (OE/EO).
