Connection of this power supply to an AC power
source should be made by a qualified electrician or
other qualified personnel. Incorrect wiring may
damage the power supply or cause a fire hazard
Fuse Requirements
An AC input fuse is necessary when powering the instrument. Refer to the table below for the
fuse requirements.
15AT / 250V (6 x 32 mm slow blow ceramic tube fuse)
Table 2.1 – AC Input Fuse Table
Fuse Replacement
Follow the steps below to replace or check the fuse.
1. Locate the fuse box in the rear panel, next to the AC input receptacle.
2. Use a flat blade screwdriver and turn the fuse capsule counter-clockwise. There is an
internal spring that will push it out after turning a few times.
3. Pull out the glass tube fuse inside to check and replace as necessary.
4. Insert the fuse capsule in the same location and use the flat blade screwdriver to turn
clockwise.
5. The fuse capsule will now be locked and secured.
2.2 Output Connections
The main DC output terminal is a screw type terminal located in the rear panel. Figure 9 below
illustrates the size and dimensions of the terminal. To loosen, use hex key #4 size screwdriver.
Note: The screws on the terminals can be completely removed to allow for ring type adapters
(must be greater than 6mm in diameter).
Before connecting wires to the output terminals, turn OFF the power
supply to avoid damage to the instrument and the device under test
(DUT). For safety, load wires must have a wire gauge size large enough
to prevent overheating when the power supply operates at maximum
short circuit output current. It will also prevent large voltage drops
