MAIN FEATURES
• Single or dual power supply configurations allow a wide range of output voltages:
Single power supply configuration:
≥12 V DC, ≤36.0 V DC input, powering both controller and TE device.
Dual power supply configuration:
≥12 V DC, ≤36.0 V DC at 150 mA minimum for controller circuitry
≥0 V DC, ≤36.0 V DC for TE device.
• Pulse-width modulated output: square wave, approximately 337 Hz, with soft start.
• Maximum output current: up to 20 A to thermoelectric device and up to 2.0 A per alarm circuit, 20 A maximum
combined output current (Note: controller does not have internal fuse protection).
• Analog signal-level output: provides true linear power control capability when used with a programmable linear
power supply.
• Bipolar (heat and cool) PID control.
• Best-case control stability ±0.01 °C (when controlling a cold plate).
• Proportional (P) bandwidth adjustment: 0.5 °C to 100.0 °C.
• Integral gain (I) adjustment: 0.00 to 10.00 repeats per minute.
• Derivative gain (D) adjustment: 0.00 to 10.00 cycles per minute.
• Built in Ramp / Soak with user programmable steps in PID mode, with separate PID parameters allowed for each
program step.
• Energy-saving Proportional + Deadband control mode allows the user to program a dead band where no cooling or
heating is required, then gradually applies cooling or heating power only as necessary.
• User programmable temperature sensor curve—allows for the use of a variety of thermistors or IC type sensors
(LM335, for example).
• Separately selectable temperature sensor types.
• Temperature control ranges:
1. -20 °C to +100 °C using the MP-3193 thermistor supplied with the controller. Additional control ranges for
optional thermistors are:
a. -60 °C to +110 °C using a 5k-1 TS-141 curve (firmware revision J or earlier will provide a control
range from -40 °C to +70 °C).
b. -20 °C to +85 °C using the 10k-1 TS-91 curve.
c. -15 °C to +80 °C using the 10k-2 TP-53 curve.
d. 0 °C to +150 °C using the 50k-1 TS-104 curve.
e. +25 °C to +199 °C using the 230k-1 TS-165 curve.
• (When using one of these control ranges, the thermistor you choose must have the same
response that matches the corresponding resistance-versus-temperature curve shown in the
appendix of the manual. A thermistor following the 10k-2 TP-53 curve, for example, is not a standard
product offered by TE Technology and must be purchased separately from a third party. Other
thermistors are available from www.tetech.com.)
2. Used defined sensor table can be used to provide a custom control range for use with different sensor
types.
• Optional secondary sensor input for sensing an alarm condition.
• Two available alarm outputs, capable of sinking up to 2 A each, for triggering alarms based on the primary (control)
sensor and/or secondary sensor.
• Enable/disable interlock: can be used with thermostats to shut off output power.
• Fan speed control: Alarm 1 output can be configured as a programmable PWM fan control for two-wire or three-
wire fans that are specifically designed for speed control.
• Operating temperature range (non-condensing, vertical orientation):
Minimum: 0 °C
Maximum: 45 °C
• Back-lit Liquid Crystal Display (LCD).
• USB (Universal Serial Bus) Interface.
