datasheet
The KPS-DC-AC-70 is a 60Vac to 70Vac sine wave output inverter with a frequency of 50Hz.
The KPS-DC-AC-70 inverter is built around two cascaded converters. The first DC-AC converter delivers an intermediate voltage from the input voltage. This intermediate voltage is transformed and provides an AC voltage at the output.
The input is protected against reverse polarity by fuse and against input undervoltage by shutting down the unit.
The power supply has a test button that allows the output voltage to be activated while the button is held down.

datasheet
Description :
The KPS-DC-AC-750 is a 120Vac or 230Vac sinusoidal output inverter with a frequency of 50Hz or 60Hz.
The inverter has galvanic isolation between input and output.
The KPS-DC-AC-750 inverter is built around two cascaded converters. The first DC-DC converter delivers an intermediate voltage from the input voltage. This intermediate voltage is inverted and allows the output voltage and frequency to be provided by the DC-AC converter.
The input is protected against reverse polarity by fuse and against input undervoltage by shutting down the unit.
The output is protected if the average power is exceeded or if the peak current is exceeded. The unit is shut down when it exceeds the operational limit curves for more than 1 second. Every 2 seconds after shutdown, the unit attempts to restart up to 3 times. If the fault persists, the unit remains shut down until the input is reconnected.

datasheet
Description :
The KPS-DC-AC-1500 unit consists of single-phase sinusoidal DC/AC inverters with galvanic isolation between input and output
The unit allows:
• Selection of output frequency 50/60Hz by DIP switch.
• Local/Remote mode selection by DIP switch.
• Stop the output by applying a voltage between terminals 3 and 4 of the “signal” connector (ON/OFF).
• local signaling by green LED for OK output
• Local alarm, red LED ON when:
• fault on the output voltage.
• output current > ALARM CURRENT.
• Input voltage out of range.
• Output shutdown by overload or remote OFF command.
• Alarm. Contact open if the output voltage is not correct.
The KPS-DC-AC-1500 is equipped with protections for exceeding the average power or peak current. This protects the unit even in the event of a short circuit on the output. It also has a shutdown function if the input voltage is too low, which helps protect the batteries from harmful discharge.

datasheet
Description :
The device consists of a three-phase, sinusoidal DC-AC inverter with galvanic isolation between input and outputs.
The device includes:
●2 operating modes, configurable by the switch
● Shutdown by applying a voltage of 15 to 154 V to pins 3 and 4 of connector J4
●Monitoring of input and output status via 2 solid state relay contacts.
●The device is internally equipped with protection that monitors the maximum average power and also the maximum output current. This protects the semiconductors even in case of a short circuit of the output.
●The inverter also includes an undervoltage monitoring function (which can be disabled) on the input. This protects the input batteries from harmful discharges.

datasheet
Description :
The KPS-DC-AC consists of a three-phase, sinusoidal DC-AC inverter with galvanic isolation between input and outputs.
The device allows:
●Switch the output frequency by DIP-switch-1 of SW3. OFF: 50 Hz (default) or ON: 60 Hz.
●Switch Local/Remote mode by DIP-switch-2 of SW3. OFF: Local, ON: Remote (control by RS232).
●Shutdown by applying a voltage of 15 to 143 V to pins 3 and 4 of connector J4
●Monitoring of input and output status via 2 solid state relay contacts.
●Configure and monitor parameters via RS232.
●Start motors via a soft-start function. At start-up, the output voltage increases linearly from 0 V to the configured voltage and the frequency varies from the initial frequency to the configured final frequency.
●Set the rotation speed of a motor according to the correct voltage/frequency ratio.
●Configurable inputs (terminals 1 and 2 of J4):
-Reverse mode: allows you to change the direction of rotation of a motor by applying a voltage of 15 to 143 V.
-Average power mode: allows you to change the output frequency in V/F mode, from the nominal value to the average power value by applying a voltage of 15 to 143 V.
The KPS-DC-AC is internally equipped with protection that monitors the maximum average power and also the maximum output current. This protects the semiconductors even in the event of an output short circuit.
The inverter also includes an undervoltage monitoring function on the input. This protects the supply batteries from deep discharge.
