The Marlow Industries SE5020 is a precision temperature controller and power supply that combines programmable PID control with linear bipolar output architecture to manage thermoelectric cooling devices across demanding thermal applications. Operating over a -99.9°C to 150.0°C range with ±0.1°C stability, it delivers up to 192 W of output power and supports multiple control modes including automatic temperature regulation, PID ramp-to-setpoint, and manual constant-current operation.
Technical Specifications
The SE5020 provides 0 to ±12 Adc output current with voltage compliance from 0 to ±16 Vdc at 12 A, extending to ±21 Vdc at 1 A. Temperature control stability reaches ±0.1°C typical, with calibration accuracy of ±0.5°C and linearization accuracy of 0.1°C for thermistor and 0.2°C for thermocouple inputs. Ramp rates span 0.01°/min. to 99.99°/min., allowing precise thermal profiling. Output ripple and noise remain below 10 mA rms. Voltage and current readout accuracy is 1% of reading plus two digits.
The unit accepts dual AC input supplies: 104–125 Vac or 208–250 Vac at 48–62 Hz, drawing 4.8 A maximum at 115 VAC and 2.4 A maximum at 230 VAC. Operating temperature is 0°C to 50°C; storage range extends to -10°C to 50°C.
– Key Features
• Thermistor (four types) and Type T thermocouple sensor compatibility
• Three independent four-digit LED displays for parameter readout
• Red/green bar graph indication for heating and cooling modes
• High, low, and deviation limit alarms
• Optional RS-232-C or RS-422-A remote programming and readout
• Benchtop operation with tilt-up stand; optional 19″ EIA rack mount adapter
– Typical Applications
Laser diode thermal stabilization, infrared detector temperature management, CCD camera cooling, and thermoelectric heat exchanger control all benefit from the SE5020’s precise regulation and low-noise output.
– Compatibility & Integration
Front panel controls enable direct manual and automatic mode operation. Remote interfaces optionally extend command and telemetry capabilities. Physical dimensions of 5.22″ H × 8.38″ W × 16.0″ D (13.3 cm × 21.3 cm × 40.6 cm) and 30 lbs (13.64 kg) weight accommodate laboratory benches and standard instrument racks.
