DETAILED SPECIFICATIONS

............
Turn-on delay : Less than 1 sec between application of power and rise of all output DC voltages to nominal value.
Minimum loading: A minimum load of 10% at nominal line is required on the primary output units to ensure regulations of auxillary outputs
Overvoltage protection: The inverter shuts down whenever an overvoltage condition exists on any output. Trip point is set to 120-135% of nominal. OVP circuit is reset by cycling AC power.
Overload protection: instantaneous current limiting type circuitry. short circuit current is approximately 20 to 100% of rated load. Protection is continouos without damage. Output recovers automatically upon removal of fault condition.
Remote sense: Compensates for output line of up of 500MV  on main output and up to 250MV on high current auxillary outputs. Open sense lead and reverse sense lead protection are provided. Open sense lead condition will not cause outputs to deviate more than 5%. reversed lead condition will not cause catastrophic failure.
Output isolation: All outputs are independently isolated and may be referenced up to 50V from chassis ground.
Load capacitance: All outputs exhibit stable performance under all specified operating conditions when remote sense is loaded with a capacitance of 3 to 8/uf per load Ampere.
No load protection: Operation without load current on any or all outputs will not reduce reliability or otherwise impair performance when loads are reapplied.
General and Environmental
Efficiency: Typical 75% for single output units and 70% for multiple output units.
Parallel operation: Units may be directly paralleled(no master) and current shared to ensure that no single unit is overstressed  (main output only) Auxiliaries may be paralleled as an option.

Thermal protection: Automatic shut down when internal temperatures exceed maximum safe ratings. Automatic reset when temperature returns to acceptable level.
Storage temperature: -55° to +85°C
Operating humidity: 0-95% without condensation.
Temperature coefficent: 0.02%/ °C maximum for all outputs.
Reversed voltage protection: Output is inherently protected against reverse output voltage up to the full current rating of the unit.
Power factor: Typical 0.65
Cooling: Forced convection using internal fan. Compliance to all specifications with reverse air flow.
Interface signals
Power fail detection: Upon loss of AC Input power of TTL compatible signal (logic 0) is provided which is referenced to the primary output negative sense terminal. Signal appears at least 2 msec prior to the primary output dropping 5% below normal.see graph
Power on/off Sequence
Power fail signals for all outputs
True (>= 2.5V)
False(<0.4V)
T1 < 10 Sec  T2 > 2 mSec
T3 > 30 mSec  T4 > 0 mSec when remote output is used
T4 < 1µSec
power fail (0) sink current = 2 mA max.
power fail (1) source current = 400µA max.

Remote inhibit: Units may be remotely turned on with an open circuit (logic 1) and turned off with a switch colsure (logic 0) reference to the primary output negative sense terminal.
Current monitor: Signal allows monitoring of parallel operating units as an indiaction of load sharing.
Remote programming: Primary output voltage may be remotely programmed ±4 to 8% ( nominal ±6%) for system margin checking. This function is referenced to the   primary output negative sense terminals.
DC OK : Signal is referenced to the primary output negative sense terminal and remains high ( logic 1) as long as the primary output is within ±5% variation, signal goes low (logic 0) sink current to 20 mA.
OVP actuated: When any OVP is activated this signal goes low (logic 0) with respect to the primary output negative sense terminal.
Logical inverse: Available on the front panel of the 1000 thru 1800 watt units. it is logical inverse of all signals.
