TE Technology TC-36-25-RS232 - Manual (Page 10)

Main Features
• RoHS compliant
• Operates as a stand-alone controller or with a computer monitor
• Bi-directional, solid-state H-bridge operation for both heating and cooling
• Can be configured to control both high and low voltage thermoelectric (TE) devices:
 Single power supply configuration for TE devices with an input voltage range from (12 to 36) VDC
 Dual power supply configuration for TE devices with an input voltage range is less than 12 VDC:
o
Controller-circuitry input voltage range from (12 to 36) VDC
o
TE device (H-Bridge) input voltage range from (0 to 36) VDC
• Maximum 25 A current rating, controls up to 900 W
• Soft-start features turns the output on slowly, over a one second period
• Over current shutdown that can be set in 2.5 A increments
• Open sensor and shorted sensor output shutdown with automatic restart
• Low Voltage shutdown protects the H-bridge when the control circuitry voltage is less than 12 VDC
• Pulse width modulation of output at 2700 Hz
• Computer programmable via RS232 communications port
• Control temperature of –20 °C to +100 °C using thermistor supplied with controller
• Control temperature of –40 °C to +250 °C using optional thermistors
• Proportional (P), Integral (I) and Derivative (D) control that can be selected as P, PI, PD or PID; or Deadband (on/off) with an adjustable
hysteresis
• Temperature resolution of 0.01 °C or 0.01 °F
• Control stability of ±0.01 °C or ±0.01 °F (best case, when controlling a cold plate)
• Set temperature adjustable by several options:
• Computer set via software/RS-232 communication
• Remote potentiometer (customer supplied)
• 0 mA to 20 mA current loop
• 0 VDC to 5 VDC adjustable range
• Differential temperature control (allows control to a programmable temperature difference above or below the temperature of the
second thermistor, if used)
• MP-2986 Display and Keypad (optional accessory)
• No computer programming experience required to use the communications software program
(Supplied software is compatible with Windows 7 and Windows 8)
• Command set is provided so programmers can create their own software interface or embedded controller applications
• Versatile alarm system:
• Computer configurable alarms for 25 mA, with a compliance voltage up to 11 VDC
• Alarm cancel: selectable via computer-software communication or remote contact closure
• The second sensor input is configurable as a heat-sink over-temperature shut-down
• Non-volatile memory retention of parameters (1,000,000 write cycles maximum; see command #34 in Appendix C for further details.)
• Operating temperature range of 0 °C to 60 °C, storage temperature range of -55 °C to +105 °C
