Order numbering code
The current ratings of the power supplies,
5 A, 10 A, 20 A and 40 A, can be made
available at an operating voltage of DC
24 V. This corresponds to the power
classes 120W, 240W, 480W and 960W.
They are suitable for an ambient
temperature of up to 70°C at an efficiency
of up to 93%.

A complete kit from a single source
The SMP product group consists of a
single- or three-phase supplied AC power
supply and is the central component of
the DC 24 V level which is composed as
follows:
● AC primary circuit protection by means
of the MCB type 4230-T
● primary switch mode power supply type
SMP with output voltage DC 24 V
● protection of the DC 24 V load circuits
by means of mechanical and electronic
circuit breakers and protectors
2.1/2.2
Factory automation today in machine
construction and process control widely
uses switch mode power supplies. The
powerful switch mode power supplies
type SMP for DIN rail mounting are an
ideal completion of the E-T-A product
range for the DC 24 V control voltage level.
The SMPs perfectly match our electronic
circuit breakers and protectors type
ESS20, ESX10, ESX10-T and REF16-S
with integral current limitation.
