TEC48V10A — 48V, 10A High Voltage TEC Controller / Peltier Driver

Q: What is the TEC48V10A high voltage TEC controller?

The TEC48V10A is a compact, high-efficiency thermoelectric cooler (TEC) driver module and the highest-voltage member of Analog Technologies' high-power TEC controller family. It is powered by 5.5V to 48V DC and delivers ±10A bidirectional output current with an output voltage range of 0 to ±47.5V, achieving over 92% efficiency.

Q: What is the difference between TEC48V10AD and TEC48V10ADAPID?

TEC48V10AD uses a traditional analog compensation network that the user tunes manually for the thermal load. TEC48V10ADAPID adds built-in Auto-PID firmware that automatically tunes the compensation loop, eliminating the need for manual tuning. Both share the same DIP package and electrical performance.

Q: What temperature stability can the TEC48V10A achieve?

When paired with a suitable temperature sensor and a properly designed thermal load, the TEC48V10A achieves better than ±0.001°C temperature stability.

Q: Which temperature sensors does the TEC48V10A support?

The TEC48V10A supports thermistors (NTC), RTDs and temperature-sensor ICs. The sensor type can be selected to match the application.

Q: Does the TEC48V10A require an external heat sink?

No external heat sink is required for output currents below 8A. For currents above 8A, an external heat sink is recommended to keep the controller's internal temperature below 85°C. The module also includes thermal pads underneath that can be soldered to inner PCB layers as a built-in heat sink.

Q: What makes the 48V version useful versus the lower-voltage models in the family?

The 48V supply lets the TEC48V10A drive much higher-voltage TECs (up to ±47.5V across the TEC) than the 24V or 28V members of the family. This is ideal for stacked TECs or large multi-stage modules that need high voltage drop at moderate current — for example, large laser-diode arrays, large optical assemblies, scientific cold heads, or wide-dT thermoelectric stacks. Power supplies built around 48V telecom or PoE rails can drive the controller directly without a step-up converter.

Q: When will the TEC48V10A be available for purchase?

The TEC48V10A is currently in pre-release. Please contact Analog Technologies via sales@analogti.com for sample requests, expected release date, and OEM pricing.

NEW — The TEC48V10A is the highest-voltage member of ATI's high-power TEC controller family. It accepts a wide 5.5–48V DC supply (telecom/PoE-compatible 48V rails work directly) and drives TECs at up to ±47.5V / ±10A with >92% efficiency and <±0.001°C stability. Ideal for stacked TECs, large multi-stage Peltier modules and wide-dT thermoelectric loads. Currently in pre-release — contact sales@analogti.com for sample requests and expected ship dates.

Description

A Thermo-Electric Cooler (TEC), also called a Peltier device, is a solid-state semiconductor that cools or heats a thermal load by adjusting the magnitude and polarity of the current flowing through it. The TEC48V10A is a high-voltage, high-current TEC controller specifically designed to manage the operation of a TEC, maintaining the target object's temperature within a precise range around a set value. This high level of temperature control is achieved by adjusting both the direction and magnitude of the current supplied to the TEC.

The controller operates with a DC input voltage between 5.5V and 48V, and is capable of delivering up to ±10A of output current with an output voltage range of 0 to ±47.5V. It uses a PWM-smoothed continuous output current driver and achieves >92% efficiency at full output (V_PS=48V, V_TEC=24V, I_TEC=10A). Thermal pads underneath the module allow it to dissipate heat through inner PCB layers; no external heat sink is needed for output currents up to 8A. The TEC48V10ADAPID variant adds a built-in Auto-PID compensation network so no manual loop tuning is required, while the TEC48V10AD uses a conventional analog compensation network for fixed thermal loads.

Within ATI's high-power TEC controller family, the TEC48V10A occupies the high-voltage end: where the 24V members of the family (TEC24V6A / TEC24V10A / TEC24V15A) suit TECs needing up to about ±23.5V, the TEC48V10A extends the voltage envelope to ±47.5V — double the output voltage range — which makes it the right choice for stacked TECs, multi-stage Peltier modules and high-dT thermoelectric loads driven from a 48V rail.
