Features Continued:
 User-adjustable HIGH and LOW load-current bracketing. Either high current or low current produce a fault
which is reported to the terminal strip as well as LEDs, which can then be handled as a soft fault or hard fault.
Soft means a user-provided PLC can decide what action is taken before the inverter is disengauged. A hard fault
will automatically provide an OFF command to disengage the inverter output.
 Pulse Width and Frequency control in manual mode provide for complete system flexibility.
 Onboard potentiometers to control frequency, power (PDM), and output voltage (Pulse Width) can be jumpered
in or out individually, if off-board control is desired.
 Inputs easily interface to PLC or computer. 4-20 ma input or 0-20 ma control of power (PDM) for simple and
linear ORP interface, if desired. Also, jumper configurability for 0-10vdc allows interfacing to all common
closed- loop control devices. Frequency and Voltage (Pulse Width) optionally controlled via 0 – 10vdc.
 Additional user-terminal strip interfaces: Output ON (implies no faults); scaled buss volts; scaled buss current; 1x
inverter clock frequency, soft / (latched) hard fault.
 Safety lockouts and automatic-fault shutdown should short-circuit or over-temperature conditions occur. Fault
status is latched and is reported via LEDS to aid technicians. Indicators include: Output ON, Instantaneous, and
long-term over current, over temp.
 PDM, Voltage and Frequency potentiometers have their own jumper selection for on board control if
desired.
 Push-On, Push-Off or toggle-switch control, inputs and simulates contact logic for simple management of
ON/OFF function.
 Buss-Voltage Compensation maintains nearly constant output voltage should line voltage drift. Compensation is
automatically scaled for 120v and 240v operation.
 Control connections of the essential I/O functions are the same as the SSD110 and Plasma Block®.
 Full pulse-by-pulse current limit control for all power output devices for reliable operation.
 Short input power loss ride-through stabilizes performance during line-voltage fluctuations.
 All control connections are fully isolated from power line reference to enable simple and safe connection to other
equipment.
 Normal frequency range of 50hz, adjustable to 30khz with built-in IGBT protection circuits.
Military grade conformal coating eliminates problems associated with condensation and mold as well as
greatly retarding damaged caused by accidental ozone exposure.
