The HBControls LPC-50HDS is a proportional output (phase-angle) solid state power controller, utilizing a Crydom HD4850 solid state relay and a microprocessor-based control board. Fully assembled and ready-to-use, the LPC-50HDS / HD4850 solid-state relay provides 0% to 100% power to resistive loads in proportion to the analog input provided. The LPC-50HDS is rated to 25 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 HD4850 consists of two SCRs configured in inverse-parallel (back-to-back) capable of withstanding surge currents up-to 625 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 LPC-50HDS to operate safely and reliably in harsh industrial applications with MTBF ratings in excess of 7 million hours.

 

The LPC-50HDS 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 LPC series power controllers. The LPC-50HDS is also available with a 24Vac power supply pre-assembled onto the assembly (“PS-xxx” option).

 

Operation Mode:

 

Phase Angle Control: The output of the LPC-50HDS / HD4850 will only conduct load current at certain points of the AC sine wave. The point at which it begins to conduct is dependent upon 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, then the output will turn on at the peak of each AC sine wave, 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 the power to 40% by only conducting load current once 60% of the AC sine wave had passed.
