MT Series IV: Controls
Analog Control - A Series
MT Series models utilizing the A Version front panel, MTA, provide stepless analog control from front panel potentiometers. With simple configuration changes, voltage, current, over voltage trip, and over current trip may be programmed from the rear connector or with RS232, optional IEEE-488, or optional Ethernet communications. MTA Series power supplies are well suited for industrial applications requiring a minimum of control.
Digital Control - D Series
MT Series models utilizing the D Version front panel, MTD, provide all of the features of the A
Version plus these models can be configured for keypad entries and up/down presses for voltage,
current, over voltage trip, and over current trip. Key strokes are kept to a minimum by a repeat
last command feature. MTD Series power supplies are well suited for laboratory applications
requiring enhanced control.
MTD Series models have one-hundred memory states available to program voltage, current, over
voltage trip, over current trip, and time period. Set points can be auto sequenced with time or
external triggering. Special programming codes allow repeating to create a power function
generator. The first 10 memory states are displayed on the front panel to simplify programming
tasks.
MTD Series power supplies offer an analog input to modulate the voltage or current setting using
piecewise linear approximation. This feature enables the voltage or current setting to be adjusted
by a sensor input, such as a thermistor, or by monitoring its own voltage or current. Modulation
allows the output to be tailored for advanced process control applications, battery charging, and
source emulation.
Computer Control - C Series
MT SERIES models utilizing the C Version front panel, MTC, only allow control from the rear connector or by RS232, optional IEEE-488, or optional Ethernet communications. These models are intended for process control applications where front panel controls and displays are not required or desired.

Isolated External I/O for Automation
Using the rear 37-pin I/O connector, the MT Series power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage trip, and over current trip set points are set by applying a 0-10 Vdc signal. Each diagnostic condition is given a designated pin, which reads 10 Vdc when high. Also, the power supply features an external interlock, which when enabled, allows the power supply to be tied in with other emergency stop equipment. All these pins are isolated to earth-ground as standard--no additional isolation equipment necessary!
LXI-Certified Ethernet Option 
LXI is an instrumentation platform based on industry standard Ethernet technology designed to provide modularity, flexibility and performance to small- and medium-sized systems. LXI’s advantages are exemplified in its compact, flexible package providing high-speed I/O and reliable measurements. These features meet the needs of R&D and manufacturing engineers delivering electronics for the aerospace/defense, automotive, industrial, and medical markets.
Certified to the LXI Standard (Class C), the XR Series Ethernet option includes an embedded web-server, allowing web browser power supply control and monitoring from virtually anywhere.
