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
RS‐485 communication protocol
Computer programmable settings and monitoring
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:
o
Computer set via software
o
Remote potentiometer (customer supplied)
o
0 mA to 20 mA current loop
o
0 VDC to 5 VDC adjustable range
o
Differential temperature control (allows control to a programmable temperature difference above or below
the temperature of the second thermistor, if used)
o
MP‐2986 Display and Keypad (optional accessory)
No computer programming experience required to use the communications software program (Supplied
software is compatible with Windows 95/98/XP/NT)
Command set is provided so programmers can create their own software interface or embedded controller
applications
Versatile alarm system:
o
Computer configurable alarms for 25 mA, with a compliance voltage up to 11 VDC
o
Alarm cancel: selectable via computer‐software communication or remote contact closure
