1. Introdu tion
This chapter describes the general characteristics and main features of the EASY-
DRIVER digital bipolar power supply series.
1.1 EASY-DRIVER Overview
High efficiency, extreme reliability, overall performance and easiness of
configuration and maintenance are the key features of the EASY-DRIVER power
supply units.
The EASY-DRIVER series has four commercially available current-controlled
digital bipolar power supply modules:
- EASY-DRIVER 0520, rated at ±5A@±20V output;
- EASY-DRIVER 1020, rated at ±10A@±20V output.
- EASY-DRIVER 0112, rated at ±1A@±12V output;
- EASY-DRIVER 0220, rated at ±2A@±20V output.
Each power supply unit fits in a single 19-inch 1U crate and implements a
completely digital control loop with a specific Pulse Width Modulation (PWM)
generation technique that makes the system extremely versatile and easy to “tune” to
any load condition.
Each power unit is composed as follows:
- an auxiliary AC/DC section that powers up the control electronics;
- a power AC/DC section that feeds the DC/DC output power stage electronics;
- a full-bridge DC/DC section with a control-communication section, made up
by two different Digital Signal Processors, signal conditioning stages and a
power section are implemented;
One of these two DSP performs the current control loop while the other one
supervises all processes as communication, diagnostics and interlock handling.

EASY-DRIVER – User’s Manual

Remote communication is guaranteed by means of an Ethernet 10/100 auto-
sensing socket accessible from each module front panel.
1.2 System Parts
The EASY-DRIVER unit is housed in a 1U – 19” crate that has embedded
cooling (front-to-rear air flow). The front panel of the EASY-DRIVER is shown in
Figure 1 .
Figure 1: front view of the EASY-DRIVER unit
Output connections, interlock and status signals and the AC Mains Power socket
are all placed on the rear panel of the power supply crate as shown in Figure 2 .
Figure 2: front view of the EASY-DRIVER unit

DC Output connectors are terminal-type ones that allows for easily connecting
direct cables (suggested cross sectional area for load cables is rated at 6 mm
2
, or AWG
10 – AWG 9).
The output connection terminal direction is indicated as shown in Figure 3 .
Figure 3: output connection of the EASY-DRIVER
The LEDs, visible from the power unit front panel (shown in Figure 4 ), are
indicators of the power supply status and have to be interpreted as follows:
• DC LINK LED: the green light indicates that the bulk power supply is working
correctly;
• AUX PS LED: the green light indicates that the control electronic section
voltage – i.e. 3.3V, directly obtained from auxiliary AC/DC – is correctly
working;
• RX LED: the green light toggles at every character reception and it is a
communication heartbeat indicator;
• DIAG LED: the green light toggles at every diagnostic routine execution. If this
LED is not toggling, the internal diagnostic routines are not correctly performed
by the module.
• ON LED: the blue light indicates that the EASY-DRIVER output turned on and
it is correctly regulating output current;
• FAULT LED: the red light indicates that the power supply has experienced a
generic fault that can be either an internal protection trip or an external interlock
intervention. This light does not turn off after a fault until a module reset has
been performed.
It is important to notice that the blue ON light and the red FAULT light cannot
be turned on at the same moment because the module cannot correctly regulate output
current if a fault is experienced and the output stage of the power supply is disabled.
