Signet 7310 Switching Power Supplies provide
regulated output voltage in compact and lightweight
plastic housings for DIN Rail mounting. The series
includes five different output capacities from 0.42A
to 4A (10W to 96W), all of which accept universal AC
line voltage input and meet worldwide standards
for performance and safety. These units meet the
power requirements for a single system, multiple
Signet instruments or other devices requiring 24 VDC
operation.

Note

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 °C of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.

Accessories and Replacement Parts

DIN rail in one meter (1000 mm) lengths, and DIN rail clips are available. The standard packaging of these power
supplies are to be fastened to DIN rails, and accessory clips will keep the supplies from sliding if the rail itself is
mounted vertically, for example. Contact the factory for more details.
