1. IMPORTANT SAFETY INSTRUCTIONS

1. Do not use this apparatus near water.

2. Clean only with dry cloth.

3. Do not block any ventilation openings.

4. Do not install unit near any heat source or heating emitting d evi ces.

5. Prevent the power cord from being walked on or pinched.

6. Unplug this unit during lightning storms or when unused for long periods of time.

PRECAUTIONS

1. The unit must be used within its specified range.

The rated input volt ages can be found on the rating label at the back of the unit. Before plugging into the AC supply, check with the rating label.

2. This unit has a built-in Tracking O.V.P. (Over Voltage Protection) f ea tur e . I n the e ve nt of the output voltage be c om ing 10% greater than the se t

value, the O.V.P. wi11 be triggered and the output power will be cut off and > FAULT< warning will appear. When you get this warning, switch off the unit and remove all loading. If you switch the unit back on again it should resume normal operation. In the event that this problem persists contact the manufacturer.

3. This unit has a buzzer built inside. The buzzer will sound when Over Temperature/Overload/Over Voltage Protection has been triggered.

When you get this warning, switch off the unit and remove all loading. Check your load and output voltage setting. Allow the unit to cool down for 30 minutes. If you switch the unit back on again, it should resume normal operation. In the event this problem persists, the unit must be investigated by your agent.

4. Only use the supplied software and optional accessories with this unit.

5. Refer all servicing to manufacturer.

Warning! The maximum output voltage for Model 1698 is up to 60Vdc. It may be hazardous to touch metal part of the terminals.

3. INTRODUCTION

This series of laboratory grade, switching mod e, p rogr ammable p ower su p pl ies are i deal for rep eti tive test ro u tin es i n R&D , Produ ction, Product Evaluation and various applications.

Information appearing on the large back-lit LCD makes the panel controls simple and easy to use in spi te of its sophisticated features.

Because of the MCU (Micro-Controller Unit) and the related softwar e, user re-calibration without opening the case is an added bonus.

When used with a standard PC, the supplied user friendly software and built in RS-232 interface provides two way communications improving the functionality of these units.

Data logging with color graphic display in adjusting range Voltage, Current, Watts, and time periods are all valuable tools in data analysis.

Please keep this manual in a safe place and contact the manufacturer for any special requirements in appli cation software or other features.

5. GENERAL OPERATION PRINCIPLE

There are four operation methods for this unit:

• Manual Operation

• Presets

• Timed Program

• PC Interface Mode.

•

The large Liquid Crystal Display will guide you through the various operations/procedures interactively once you understand the operation principle.

There are four Dual Function Control Keys for various operation modes and input states of the unit.

To change/set operation mode (output on /off, key lock & etc.), in most cases you need two Dual Function keys to complete the operation. To change input values of various settings (voltage, current, preset number, cycles, time period & etc.), use the ENTER key to get ready and confirm the new settings.

Liquid Crystal Display

The back-lit display shows both the preset and the actual voltage, current levels at the output terminals; and status of constant current (CC) or constant voltage (CV) mode. Be aware of new symbols appearing on the display while inputting. They will guide you and remind you of the correct procedure.

Example: Inputting values of various settings

When a new setting (voltage, current, time periods & etc.) is ready for inputting, the symbol for the related setting will appear on the display. After you key in the required value, always follow by pressing ENTER to confirm or to complete the operation.

Presets and Timed Subprograms

This unit has the capacity to store 10 programs.

Program 1 to 9 is for nine sets of Presets of voltage and current. The program 0 is reserved for the 20 timed subprograms; ea ch is capable of storing 1 second to 99-minute operation period with its preset voltage and current levels. The timed subprograms can be set to operate repeatedly in sequence from 1 to 232 cycles.
