CAEN will repair or replace any product within the guarantee period if the Guarantor declares
that the product is defective due to workmanship or materials and has not been caused by
mishandling, negligence on behalf of the User, accident or any abnormal conditions or
operations.
CAEN declines all responsibility for damages or
injuries caused by an improper use of the Modules due
to negligence on behalf of the User. It is strongly
recommended to read thoroughly the CAEN User's
Manual before any kind of operation.
CAEN Technologies reserves the right to change partially or entirely the contents of this
Manual at any time and without giving any notice.
Disposal of the Product
The product must never be dumped in the Municipal Waste. Please check your local
regulations for disposal of electronics products.
MADE IN ITALY : We stress the fact that all the boards are made in Italy because in this globalized world, where getting the
lowest possible price for products sometimes translates into poor pay and working conditions for the people who make them, at
least you know that who made your board was reasonably paid and worked in a safe environment. (this obviously applies only
to the boards marked "MADE IN ITALY", we can not attest to the manufacturing process of "third party" boards).

1. General description
1.1 NIM8300 crate series
The NIM8300 crate series consists of a NIM mechanics and a pluggable power supply
(150W, 300W, 600W, 1kW and 2kW available). NIM standard, despite of its age, is still a
great choice for building a small and flexible setup for high resolution measurements with
analogue electronics such as amplifiers, ADCs, timing and logic units and also LV/HV
power supplies.

1.2 NIM8304 Overview
The CAEN Mod. NIM8304 is a 7U (5+2) full size NIM crate (19”-12 slot) with switching
1.1kW US and 2.2kW EU power supplies. The units are ventilated by a pluggable 2U fan
unit.
Safety features include: short circuit protection, Over / Under voltage protection, Over
temperature protection. Remote monitoring and control take place through CAN bus,
Ethernet, USB and RS232 interfaces. The crates are also SBC controlled via graphic
OLED Display. User-friendly control software completes the NIM 8304 features. The Unit
is powered by 115 or 230 Vac, 50 ÷ 60 Hz.

3. Power Supply section
The CAEN NIM Power Supply is micro-processor controlled switching power supply,
which provides extremely low noise output voltage.
Fig. 3.1: Mod. NIM8304 Power Supplies Front an Rear view
the NIM8304 power supplies are composed of the following modules ( see Fig. 3.2.)
-Power Factor Correction module (PFC)
-Power modules
-Power supply controller
The power modules are readily replaceable. The maximum output power is 1100÷2200W
with 92 ÷ 264 V input voltage.

3.2 Power Factor Correction Module (PFC)
The mains input includes a Power Factor Correction Module (PFC) with main filters, soft
start- circuit and fuses. an external fuse or circuit breaker has to be installed with a
capability of 16A.
The AC input module is permanently powered after connecting the unit to the AC- mains.
Switch ON/OFF activates only the DC on/off function of the power inverter modules.

Turning on the power supply all voltages reach the nominal values nearly simultaneously
within 50 ms whereby the voltage versus time curve shows a monotonic behavior. The
start-off-time which corresponds to a value of 10% of the nominal voltages is reached
after 50 ms. The turn-on inrush current is limited by a soft start-circuit to a maximum
value of 16 A.
The power modules are readily replaceable. The maximum output power is 1200÷2530W
with 92 ÷ 264 Vac input voltage.
3.3 Mains Voltage and Connection
The Power supplies are equipped with a “World”- mains input, which works properly from
92Vac up to 264Vac and within a frequency range of 50 to 60Hz. Before connecting to the
mains please double-check correspondence. Mains input connection at the power supply
side is done with a 3-pin “Hirschmann” 16 A connector or power terminals.
