Standard Features of 2000-Watt PSI2000N Series Pure Sine Wave Inverter
DC INPUTS: Positive (+) and Negative (-) input terminals are 3/8″ studs with brass hardware. They are accessed under the rear cover. Use “Appendix A” to choose the appropriate gauge wire for your specific model.
REMOTE ON/OFF: Provides the user with a remote method to turn the inverter on and off. “REMOTE” connection is on the barrier terminal strip located under the rear cover.
AC OUTPUTS: All domestic models have two NEMA –
PSI2000N Series Pure Sine Wave Inverters will have an IEC-320 receptacle located on the front panel. Additionally, the unit may be hard-wired to appliance/load using connections on the barrier terminal strip, located under rear cover.
COOLING: Provided by a thermostatically controlled brushless fan located on the front panel.
DC POWER ON LED: Located on the front panel, will be “ON” when PSI2000N Series Pure Sine Wave Inverters are powered up, and DC power is available.
LOW BATT/THERM BUZZER: Produces an audible alarm if DC input voltage falls to a level within 2% to 4% of the low limit of inverter, or if there is an over temperature condition.
ON/OFF SWITCH: Located on front panel; turns the inverter on and off.
OVER VOLTAGE PROTECTION: When input voltage to the inverter exceeds set limits, the inverter will immediately and without warning shut off. When input voltage returns to normal range, the inverter will immediately restart. Since high over voltages tend to have very fast edges, the inverter must shut down quickly to protect itself. This kind of fault usually occurs if the battery is suddenly disconnected from the system and the battery charger continues to supply current.
UNDER VOLTAGE PROTECTION: When battery voltage falls to within 2% to 4% of low line voltage, the LOW BAT/THERM buzzer will sound. If the condition continues without reducing load to the inverter or adding charge to the battery, the inverter will shut off. When voltage rises to approximately 85% of nominal battery voltage the inverter will turn back on and the alarm condition will clear. The inverter can be manually reset by cycling the on/off switch. This will reset the protection circuit and turn the inverter on at any voltage above minimum voltage.
OVER TEMPERATURE PROTECTION: The inverter is also protected against overheating. It will provide its full rated output up to the temperature listed in the specification sheet. If it is subjected to higher ambient temperatures or air circulation is blocked, the inverter could overheat. If the LOW BATT/THERM buzzer sounds, immediate action is required or the inverter will shut down. Either reduce load, or provide more cooling in the immediate environment. If no action is taken, the inverter will likely shut down within two minutes. When the inverter shuts down, the alarm condition will persist and the cooling fan will continue to run. Since the inverter has eliminated its load, it will quickly cool. It will automatically restart when it has cooled sufficiently, and the LOW BATT/THERM alarm will clear.
OVERPOWER, SHORT CIRCUIT PROTECTION:
PSI2000N Series Pure Sine Wave Inverters will provide peak current (45 A) or maximum surge (4000W) for three seconds when the inverter’s internal temperature is at or below 25°C . The output current is then reduced to 16.7A (rated power) for four secs. If the inverter cannot restore a full sine wave due to overload, the LED will be red. If the overload condition does not clear in seven seconds, the inverter shuts off (flashing red indicator).
