Convenient FET switches in H-bridge configuration Built-in protective Forward/Reverse interlock function UL & IEC ratings for general use & Motor loads LED Status indicators for Operating Modes

MOUNTING INSTRUCTIONS

Please read all installation instructions before using your DP Series Solid State Contactor (SSC).

Choose one of the two mounting options and follow the instructions.

Mounting on Heat Sink

Select adequate heat sink (see thermal derating

(B)

curves).

Be sure to use thermal pad or grease between the SSC and the selected heat sink.

DP Series Contactor mounting slots have a diameter of 0.2 in (5.0 mm). Four screws are needed (not included) to mount the SSC onto heat sink (See Fig.

1). Choose screw length considering the mounting surface and that DP Series baseplate thickness is

0.125 in (3.2 mm).

Before applying full torque tighten down all 4 screws until they contact the baseplate. Then, tighten them to 20 in-lbs (2.2 Nm) starting with one immediately followed by the one in the diagonally opposite corner. After the first 2 screws are completely tightened, proceed tightening the remaining 2 screws.

For optimal thermal performance heat sink fins should be oriented vertically to natural airflow.

Mounting on Panel

Locate the panel section on which the DP Series SSC will be mounted. Panel mount surface must provide adequate heat sinking capability. (B)

Be sure to use thermal pad or grease between the SSC and the panel.

DP Series Contactor mounting slots have a diameter of 0.2 in (5.0 mm). Four screws are needed (not included) to mount the SSC onto panel. Choose screw length considering the mounting surface and that DP Series baseplate thickness is 0.125 in (3.2 mm).

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 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 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 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.
