Standard Features
•
Type of Power Conversion Circuit: High frequency.
•
Constant Voltage Mode: For any initial output voltage setting from 42 to 58 volts, output voltage
remains constant regardless of load. This is the normal operating condition, in which loads are being
supplied and batteries are float charged. Solar converters operate in the Constant Voltage Mode unless
load increases to the point where the product of load current and output voltage is approximately
2000 W.
•
Constant Power Mode: As load increases above approximately 2000 W (non-adjustable), output current
continues to increase, but output voltage decreases as required to maintain constant output power.
Solar converters operate in the Constant Power Mode unless load continues to increase to the point
where the current limit setting is reached.
•
Constant Current Mode: If load increases to the current limit setting, output voltage decreases linearly
to maintain output current at the current limit setting.
•
Input Protection:
a)
Input Over/Under Voltage Protection: The solar converter will shut down at low or high voltage
input; based on the following voltage levels:
1.
Low Voltage Disable Point: 115 V, ±5 V; hysteresis is 10 VDC for restart.
2.
High Voltage Disable Point: 425 V, ±5 V; hysteresis is 10 VDC for restart.
b)
Between 120 V and 200 V the output power will be derated linearly based on the input voltage as
follows:
1.
At input voltage of 120 V with output >48 V, maximum output power is 1200 W.
2.
At input voltage of 154 V with output >48 V, maximum output power is 1540 W.
3.
At input voltage of 176 V with output >48 V, maximum output power is 1760 W.
4.
At input voltage of 200 V and output >48 V, maximum output power is 2000 W.
