PTION
For greater stability and accuracy, the Model 430 Programmer can be
configured with a zero-flux precision current measuring device instead of
the standard resistive shunt. This option typically increases the system
stability and accuracy by an order of magnitude. The power supply sys-
tems incorporating this technique are referred to as “high-stability” sys-
tems.

ESIGN
The Model 430 Programmer was designed to simplify the interface
where possible. All functions were analyzed and subsequently
programmed so that the most commonly used functions are addressed
with the least number of keystrokes. The menus are also presented in a
logical fashion so that the operation of the Model 430 Programmer is
intuitive to the user.
The provision of a velocity-sensitive rotary encoder on the front panel
also allows the operator to interactively fine-adjust many of the operating
parameters of the magnet system.

LEXIBILITY
The Model 430 Programmer can be configured with the supporting
hardware as a two- or four-quadrant power supply system which is able
to both supply and remove electrical energy from the superconducting
magnet system. The Model 430 Programmer is engineered to be
compatible with most power supplies with remote analog programming
capabilities.
From simple single-quadrant supplies, to more elaborate four-quadrant
units, the Model 430 Power Supply Programmer is user-configurable
such that the operational paradigm complies with the specific magnet
system requirements.

NTERFACES
The Model 430 Programmer provides an RS-232 serial port as well as
an Ethernet port as standard features. All settings can be controlled via
the remote interfaces and the front panel can be remotely locked to
prevent accidental operation. The Model 430 Programmer also provides
remote trigger functions for data collection and/or logging during
operation.

EATURES
The Power Supply System is designed to be operated from the front
panel of the Model 430 Programmer or remotely with operational
parameters which must not be exceeded for the given conditions of the
system. Once set, should an operator inadvertently attempt to take the
magnet system to an excessive magnetic field strength or charge at an
excessive voltage, the Model 430 Programmer will not accept the
