Sample Heater Power Supplies Sample Heater Power Supplies The LPS Series Linear Power Supplies and EPS Series Electron Beam Power Supplies provide temperature control for sample heaters. Both LPS and EPS power supplies feature a precision PID temperature controller for automated operation. These power supplies are designed for Thermionics' sample heaters but may be used to control other heaters. See specifications on this page for maximum inputs and outputs. Features PID automatic temperature control Auto-tuning Digital temperature read-out True phase fired proportional control of heater element, with manual override Adjustable minimum and maximum current limits Single programmable ramp rate and dwell time Two programmable setpoints Up to three alarm relays RS-232 interface Requires system thermocouple Specify type "K" or "C" Includes power cable, output cable, and thermocouple cable Models LPS-800 Series-- Radiant Resistive Heater Power Supply For Thermionics' /HR and/HRN heaters Samples up to 2" O.D.
