50 ac LINE VOLTAGE & CORD OPTIONS
Choosing ac Line Voltage and Cord Options
for your Agilent Power Products
High Power Products
There are several factors which limit the amount of power
which can be readily drawn from a normal branch circuit.
For example, in the U.S., the typical 115/120 Vac branch
circuit has a circuit breaker rated for 15 A. For industrial
applications, 20 A service is commonly available. Current
draw for an appliance is further restricted to 80% of the break-
er rating unless the circuit is dedicated to only one appliance.
The line cord can also represent a limiting factor based on the
wire gauge used. Finally, the power supply with a rectifier and
capacitive input filter represents a non-sinusoidal current
load. Thus, the maximum input current drawn by the power
supply is higher than if the input were a resistive load.
The practical result of this is that linear power supplies with
outputs over 500 watts and switching supplies rated over 750
watts will generally exceed the capability of a 15 A branch
circuit. Connecting power products above these power levels
will require installing either a higher voltage or higher
current service. Some practical examples are:
• standard line voltage for 2KW products such as the 667XA
is 230 Vac; they can not be powered off a 120 Vac line
• the 1KW 601XA and 603XA products cannot be powered off
a standard 15 A / 120 Vac circuit; they can operate off a
30 A / 120 Vac service, or they can be configured for 230 Vac
operation
• the 66000A mainframe requires a 30 A / 120 Vac service
or 230 Vac operation; although each module is 150 watts,
the maximum input current is based on the total
requirement of 8 modules.
Agilent offers a range of line cords for many higher power
products to mate with the wall receptacles commonly speci-
fied for these higher power services. Refer to tables 3a, 3b and
3c to determine if there is a line cord for your product with a
plug that meets the local requirements. If not, you must order
an unterminated line cord. For the products in table 3a, you
must specify a line cord option at the time you order your
power product, or an unterminated line cord will be shipped.
Often, higher power products (over 1 kW) are hardwired,
i.e. connected directly to a breaker panel or distribution box.
The line cord may also be hard wired to the back of the
power supply where a universal receptacle is impractical.
Typically, a local electrician should be consulted to determine
the best alternative to connect a high power product to the
ac line. Consider the most appropriate option for your
application based on local electrical codes.
