The HBControls TP-25HDS is a proportional output (burst fire) solid state power controller, utilizing a Crydom HD4825 solid state relay and a microprocessor-based control board. Fully assembled and ready-to-use, the TP-25HDS / HD4825 solid-state relay provides 0% to 100% power to resistive loads in proportion to the analog input provided. The TP-25HDS is rated to 15 amps at line voltages between 48Vac and 530Vac, and ideally suited to resistive heating applications where precise temperature control is desired.

 

The output circuit of the Crydom HD4825 consists of two SCRs configured in inverse-parallel (back-to-back) capable of withstanding surge currents up-to 250 amps (non-repetitive). Furthermore, the SCRs are mounted to a DBC substrate (direct bond copper), which minimizes thermal excursions and enhances overall life expectancy. This enables the TP-25HDS to operate safely and reliably in harsh industrial applications with MTBF ratings in excess of 7 million hours.

 

The TP-25HDS can accept a wide range of analog inputs, including; 0-10Vdc, 1-5Vdc, 2-10Vdc, 1-5Vdc or 4-20mA. An external potentiometer can also be used to control the amount of power applied to the AC load.

 

The microprocessor-based control board requires an external 24Vac power supply. HBControls offers a range of power supplies perfectly suited for the TP series power controllers. The TP-25HDS is also available with a 24Vac power supply pre-assembled onto the assembly (“PS-xxx” option).

 

Operation Mode:

 

Burst Fire: The output of the TP-25HDS / HD4825 provide a series a full AC cycles to the load, with the ratio of on/off cycles directly proportional to the analog input provided. For example, if the selector switch on the control board is set to 0-10V, then the percentage of power applied to the load will be directly proportional to the 0-10V analog input. If the signal is at 5V, the output will conduct load current for a few cycles and then turn off for an equivalent number of cycles, effectively applying 50% power. If the load is a heating element and the temperature starts to go beyond the set-point with 50% power being applied, then the controller might reduce its output to 4V. If so, then the solid state relay would reduce its output power to 40% by adjusting its on/off ratio to 40%.
