Operating Modes
Start: When either FWD or REV Control signal is applied, and after Control Signal Validation Delay, DC
power supply on terminals 1/- and 2/+ is directly connected to Load at terminals 3/L1 and 4/L2 with a
polarity according to the control signal. The start option can be combined with Stop and/or Dynamic
Brake options.
Stop: Load is disconnected from DC power supply. All FET switches (S1, S2, S3 & S4) inside the DP
Stop: Load is disconnected from DC power supply. All FET switches (S1, S2, S3 & S4) inside the DP
Series SSC are turned off. This simple Stop option is available only in combination with the simple
Start option (suffix Blank).
Soft Start/Ramp Up: It is a modified Start where the DC power supply is connected to the load using
Soft Start/Ramp Up: It is a modified Start where the DC power supply is connected to the load using
a 200 Hz pulse width modulation with a duty cycle going from 10% to 100%. Soft Start/Ramp Up time
is defined by SA, SB and SC suffixes. After Soft Start/Ramp Up time is elapsed, the Load will remain
continuously energized for as long as FWD or REV Control signal is applied. This option can be
combined with Soft Stop/Ramp Down and Dynamic Braking modes, but not with simple Stop.
Soft Stop/Ramp Down: It is a modified Stop where the DC power supply is disconnected from the Load
Soft Stop/Ramp Down: It is a modified Stop where the DC power supply is disconnected from the Load
using a 200 Hz pulse width modulation with a duty cycle going from 100% to 0%. After Soft
Stop/Ramp Down time is elapsed, the Load will remain continuously de-energized waiting for a
new FWD or REV Control signal. Soft Stop/Ramp Down time is tied to Soft Start/Ramp Up time
selected by SA, SB and SC suffixes and can be combined with Soft Start/Ramp Up only.
Dynamic Brake: It could be used as a modified Stop where the FET switches inside the DP Series
SSC are arranged in such a way that they provide a path for the Load Current to keep flowing after
the DC power supply has been disconnected. This mode allows for energy stored in some type of
loads to be discharged. i.e. back EMF on DC motors. Timing for Dynamic Brake is selected by
suffixes B2, B5, B8 and B where the latest will keep the braking or discharging path enabled for
as long as FWD and REV Control signals are removed.
Interlock: It will shut down all FET switches inside the DP Series SSC within 0.2 sec after both
control signals FWD and REV are applied at the same time. An Interlock condition will trigger a
modified Stop such as Soft Stop/Ramp Down or Dynamic Brake whenever an option has been
selected.
