Product Description:
The HBControls TPLP-50HDA is a proportional output (burst fire) solid state power controller, utilizing a Crydom HD4850 solid state relay and a microprocessor-based control board. Fully assembled and ready-to-use, the TPLP-50HDA / HD4850 solid-state relay provides 0% to 100% power to resistive loads in proportion to the 4-20mA analog input provided. The TPLP-50HDA is rated to 30 amps at line voltages between 48Vac and 530Vac, and ideally suited to resistive heating applications where precise temperature control is desired.
The control board of the TPLP series does not require an external power supply.
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 TPLP-50HDA to operate safely and reliably in harsh industrial applications with MTBF ratings in excess of 7 million hours.
Operation Mode:
Burst Fire: The output of the TPLP-50HDA / HD4850 provide a series a full AC cycles to the load, with the ratio of on/off cycles directly proportional to the 4-20mA analog input signal provided. For example, if the analog input is at 12mA, then the output will conduct load current for a few cycles and then turn off for an equivalent number of cycles, effectively applying 50% power.
Additional Features & Benefits of the TPLP-50HDA / Crydom HD4850 include:
- True linear output controller with selectable soft-start, suitable for resistive or inductive loads
- Line-voltage compensation with automatic 50/60Hz operation
- Compact, thermally efficient heat sink to maximize overall product life expectancy
- Direct-bond copper (DBC) substrate for superior thermal performance
- MTBF > 7 million hours (>800 years)
- Agency approvals; UL, CSA, VDE/TUV, and CE
