Only for Unigen Plus.
5.3. Connection specifications
• Power supply: 9 to 40 VDC, <1A with 12 VDC and <500mA with 24 VDC.
• AC voltage inputs: 100 to 500 VAC, 100mA max. The neutral wire can be connected or not.
• AC currents inputs: 0 to 5A, 1VA. Each input is isolated from the other ones.
• Possible over-current: 15A during 10s.
• Frequency measurement: 45 to 70 Hz – 15 VAC minimum between neutral and line.
• Digital inputs: Normally Open, to be connected to 0v (internal pull up of 10 kOhms).
• Relay outputs: 5A, 230 VAC max.
• Remote speed control input: potentiometer (5 kOhms) or -5 +5VDC.
• Remote kW control input for ‘Command mode’: potentiometer (5 kOhms) or 0 +5VDC.
• Kw monitor output (0-5 V or 0-20ma/4-20mA): the maximum load impedance for the 0-20 mA. Or 4-
20mA. is 300 Ohms and the minimum load impedance for the 0-5 VDC is 1 K/Ohms.
• Speed bias output: The frequency control is made by the adjustable 0-10 VDC output. The
adjustments are, Offset and Gain potentiometers.
• Voltage bias output: The voltage control is done via the AVR. The output is a +/-10V, output with Gain
and Offset adjustments.
• Terminals: with screws, 2.5 mm
