Page 7: Introduction
These 900W power supplies provide a variable voltage output from 1 V to 15 V at 60 A (model 1693) or from 1 V to 30 V at 30 A (model 1694). In addition, a remote sensing terminal is available for use to compensate for voltage drops due to resistances from load leads. -
Page 8: Installation
Installation Initial Inspection This unit is tested prior to shipment. It is therefore ready for immediate use upon receipt. The initial physical inspections should be made to ensure that no damage has been sustained during shipment. Inspect the packing box on receipt for any external damage. If any external damage is evident, remove the instrument and visually inspect its case and parts for any damage. -

This series has two models with different output voltage range and current. Make sure you have purchased the correct one. Model Number Output Voltage Range Total Rated Current 1693 1 – 15 V 60 A 1694 1 – 30 V... -
Page 12: Instrument Hook-Up
Instrument Hook-Up 1. Check the rating label of the power supply and make sure it complies with your AC mains voltage. Connect the power supply to the AC mains using the provided power cord. CAUTION: The AC input is double pole fusing. 2. -
Page 13: Using Both Main And Auxiliary Outputs
For example, setting the voltage output for model 1693 (1-15 V, 0-60 A) to 15 V would output 15 V at both the main and auxiliary terminals. A total of 60 A can be drawn between the two terminals. -
Page 14: Disconnection
2. Check and make sure the power connections are secure. 3. Then make connections between Remote Sensing and equipment. Figure 3 shows typical connection between power supply and device for remote sense operation. Figure 3 - Remote Sense Connection The remote sensing wire should be at least 22AWG wire size. 5.3.2 Disconnection WARNING: Wrong disconnect sequence will damage the power supply. - Page 15 Figure 4 - Remote Control Connector Solder 3 wires (22AWG) to pins 1, 2, and 3 of pin plug as shown in Figure 5. Figure 5 - Pin Numbers Make sure the load is disconnected and the power supply is OFF before continuing to the next step.
- Page 16 Figure 6 - Connector Ring Then, you can choose either method A or B below to use the analog remote control feature. Method A: Using an External Variable DC Voltage Source A variable external voltage source of 0 to 5 V is fed into the analog remote control terminal to adjust the output voltage level of both Main and Auxiliary outputs.

Method B: Using a 5 kΩ Variable Resistor 1. Make sure the load is disconnected and the power supply is OFF. 2. Prepare a 5 kΩ variable resistor and connect wires from pins 1, 2, and 3 as Figure 7 shown in Figure 7 - Variable Resistor Connection 3. -
Page 18: Maintenance
Maintenance When the Unit is Not Turning On Check if the power ON/OFF switch is turned ON. If not, then check the power cord. Please make sure that the power cord is properly connected to the unit. Please also check the main switch and ensure that the AC supply at your site is the same as the one mentioned at the rear chassis of the unit. -
