7) AC fuse
8) External Overvoltage Protectors (OVP12 module)

Jumper(s)
An external fuse (see ratings table) should be installed. Use a 125VAC or higher
rated fuse for 100-120VAC operation, and a 250VAC fuse for 220-240VAC
operation. Fuse type should be anti-surge.
In general most 5V output H Series power supplies come with internal Over Voltage
Protection. If OVP is required on other voltage outputs, then an external OVP
module should be fitted as follows:
The OVP module is user adjustable from approximately 6.2V to 34V.
The maximum current rating of the OVP12 module is 12A peak, 8A continuous.
The recommended trigger voltages are
The above table indicates Lambda’s recommended level set point for different output
voltages. Where +/- outputs exist with a common terminal, a single OVP module
located across the + and – terminals will provide functional OVP for both individual
outputs.
The OVP module comes complete with mounting hardware and hookup leads. To
connect the OVP to your supply, see your power supply’s user’s manual for
recommended placement or Lambda’s website
