The H-Bridge Driver Power Modules provides for power switching and reverse polarity outputs with a single power source (and a 5 volt control power).  

The HBD-50250-600V-5P-TTL model has a maximum withstand rating of 600 Vdc. It is designed to switch power sources up to about 300 Volts dc (with appropriately rated TVS diodes or modules) and loads up to 50 amps continuous with natural convection or 80 amps continuous with 100 CFM of air flow and ambient air temperatures to +65C.  It can handle switching 125 amps at a 50% duty cycle with 100 CFM of air flow, or 15% duty cycle with natural convection.  See the data sheet for more details. The TVS-350VB-75K is a good match for this HBD module.

The HBD-25100-1200V-5P-TTL model has a max withstand rating of 1200 Vdc. It is designed to switch power sources up to about 600 Vdc (with appropriately rated TVS diodes or modules) and loads up to 25 amps continuous with natural convection or 40 amps continuous with 100 CFM of air flow and ambient air temperatures to +65C.  It can handle switching up to 100A 1ms pulses at 10% duty cycle. See the instructions for more details..  The TVS-765VB-45K can be a good match for this HBD module.

Note: The TVS rating is the maximum practical liming factor for power source voltage on these HBD modules and needs to be rated typically about 70% or less than the HBD maximum voltage rating to provide sufficient head room for proper transient protection.

Switching transition rise and fall times are relatively fast (< 10 microseconds).

Although for most applications, it would be best practice to switch off the output prior to switching polarity, the polarity can actually be switched while the output is ON.  The control module ensures the output is OFF prior to switching ON the opposite polarity, thereby preventing a shoot through short circuit. The OFF duration delay during a polarity reversal operation is typically about 200 microseconds.

Power Connections 2 each:  One Positive, One Negative

Output Connections, 2 each:  Normal Positive, Normal Negative

Control Module Power input, 2 each:  5Vdc Positive and Return

Control Module Logic input, 2 each:  One for ON/OFF logic, One for Polarity logic, TTL compatible. For other than TTL drive signals, we have available converter modules such as a 24V to TTL.

Dimensions: 4.8" long, by 7.2" wide, by 7.0" tall.

Weight: 96 Oz., typical.
