to connect load with cos(Φ) ≠ 1 via external
contactor)
Protection: Regular circuit breaker, type B
External outputs for connection of solid state relays
SSR (S+, S1-, S2-)
0 or 5 VDC, isolated from power grid supply
SSR parameters: control DC min. 4VDC, SSR must
switch at zero (zero switch).
Protection: based on instructions specified in the SSR
relay manual
External outputs - connection with PWM function (S+,
S1-, S2-)
0 or 5 VDC, isolated from power grid supply
PWM parameters: carrier frequency 200 Hz to 10
kHz, duty cycle 0-100% in 1% steps.
Protection: based on instructions specified in the
manual of connected device
LT, FB1, FB2 and FB3 inputs
0 or 5 VDC, isolated from power grid supply.
May be switched using regular relay outputs or
optocouplers with open collector, always against
GND.
Minimum pulse width and gaps for FB inputs is 1ms.
USB Connection
USB 1.1/ USB 2.0, isolated both from power grid
