Product Overview:

Advanced Performance TEC Controller Overview

The TEC-1091 is an advanced laser diode TEC controller board that is capable of precision control of a TEC/Peltier element. It features a true bipolar DC current source for cooling/heating, two temperature monitoring inputs (1x main, 1x auxiliary) and intelligent PID control with auto-tuning. The TEC-1091 is an OEM precision TEC controller that is primarily designed to operate as a stand-alone controller embedded into a laser system or industrial product.

Auxiliary Temperature Sensors for Added Safety

This controller is configured for independent NTC (thermistor) temperature sensors. It can also be ordered configured for Pt100 or Pt1000 sensor types. The TEC-1091 is configured with an auxiliary temperature input that allow the connection of an NTC temperature sensor located on the heat sink of the Peltier element; the auxiliary sensor can be used to ensure the thermal safety of the system by preventing thermal runaway. The analog measurement circuit is factory calibrated.

Digital Interface for OEM Applications

The TEC-1091 offers numerous communication and safety options for laser diodes. It has a PC-Software that allows configuration, control, monitoring and live diagnosis of the TEC controller via USB, RS485, and RS232 TTL. All parameters are saved to non-volatile memory. Saving can also be disabled for bus operation. For the most straightforward applications, only a power supply, Peltier elements, and two temperature sensors need to be connected to the TEC-1091.

DPY-1113 Display Kit for Rapid Prototyping

The DPY-1113 TEC Status Display Kit is available to help speed prototyping efforts. The DPY is configurable via the TEC Service Software, and allows the display fields to be customized.

Part of a Complete Laser Diode Control Control Solution Portfolio

This module is part of the TEC-Family of Meerstetter TEC Controllers designed to operate alongside devices of the LDD-Family of laser diode drivers. Both families of drivers share the same system bus, design, technology and physical dimensions.

Temperature Sensor Options for Application Versatility

The TEC-1091 is available in other configurations: Pt100/Pt1000 temperature sensor inputs, Voltage sensor inputs. The TEC-1091 can be ordered with different connection options: the standard module is configured with screw terminals; also available is a SIP-pin option for direct connection to ribbon cables or another circuit board, or solder pads for direct wire connection. Inquire for details on the different configurations and a quotation.
