Specification:
1) Input detection
- Voltage: 240 V AC ±10% for 1 phase, 380 V up to 480 V AC ±10% for 3-phase, 2-wire sensing AVR Senses the true average of line to line waveform. Use Resistor (SMD) network for trouble-free sensing and control of sensed voltage/regulation.
2) Input power
- Voltage: 415V for 3-phase and 240V for 1-phase
- Frequency: 50/60 Hz
3) Output power
- Voltage: 105 V DC at 240V AC input
- Current:
• 6 Amps DC Continuous
• 8 amps for 30 sec. (when permitted by field resistance)
4) Operating temperature: -20ºC to +70ºC
5) Storage temperature: -40ºC to +80ºC
6) Voltage adjustment: min ± 10% of rated voltage.
7) Stability adjustment: adjustable to get steady state Stability good transient response.
8) Remote voltage adjustment: to obtain ±10% of the set terminal voltage (with 2W / 2.5W, 1 Watt pot).
9) Droop for parallel operation: 4% drop for 5 Amp from the «U» phase.
10) Auxiliary input A1 & A2: ±4.5V DC gives a change in the terminal voltage of ±10%.
11) Under frequency roll-off adjustment: available under 46 Hz for 50 Hz and under 56 Hz for 60 Hz.
12) Voltage build-up: ≥ 2 Volts (LN)
13) Voltage regulation: ± 0.8% at AVR terminals.
14) Thermal drift: ± 1% for 30ºC temperature change.
15) Response time: less than 50 milliseconds.
16) Closed loop response: typically 0.5 sec to recover to 98% of the set voltage for a field strength ratio of 1:2.
17) Loss of sense protection: the voltage should collapse when the sense circuit is open.
18) Over-excitation protection: 10V DC to 85V DC. Setpoint: 60 V DC
19) Fuse for protection: 6 amps, 240 volts AC.
20) All potentiometers: multi-turn except Droop pot (Droop single-turn)
