Safety Precautions

This product complies with EU directives: 2014/30/EU (EMC), 2014/35/EU (Low Voltage), 2011/65/EU (RoHS).

Observe the following safety precautions to ensure safe operation and prevent injury from short circuits:

• Before connecting to mains, verify voltage setting matches mains voltage.
• Connect only to grounded outlets.
• Do not place on damp or wet surfaces.
• Avoid direct sunlight, extreme temperatures, humidity, or dampness.
• Replace defective fuses only with the original rating; never short circuit fuses.
• Do not exceed maximum permissible input rating.
• Conduct measurements in dry clothing, rubber shoes, or on an isolating mat.
• Comply with all warning labels and equipment information.
• Keep ventilation slots clear for free air circulation; covering them can cause overheating.
• Do not insert metal objects into ventilation slots.
• Do not place water-filled containers on the equipment (risk of short circuit if knocked over).
• Do not operate near strong magnetic fields (motors, transformers).
• Avoid strong shocks or vibrations.
• Keep hot soldering irons or guns away from the equipment.
• Allow equipment to stabilize at room temperature before measurement for accuracy.
• Do not modify the equipment.
• Do not place the equipment face-down to avoid damaging controls.
• Ensure the cabinet is closed and screwed safely before operation, as terminals can carry voltage.
• Do not operate unattended.
• Clean periodically with a damp cloth and mild detergent; avoid abrasives or solvents.
• Suitable for indoor use only.
• Do not store near explosive or flammable substances.
• Opening the equipment and any service/repair work must be performed by qualified personnel. A second person trained in first aid should be present during repairs.
• Power supplies are not toys and should be kept away from children.

Cleaning the Cabinet

Before cleaning, unplug the power cord. Clean only with a damp, soft, lint-free cloth and a mild household cleaner. Ensure no water enters the equipment to prevent shorts and damage.

Introduction

These regulated laboratory power supplies feature fine adjustable output voltage (except P 6035 D) and are protected against overload and short circuits. They display output voltage and current via a 3-digit LCD (P 6035 D) or analog displays (P 6015 A) with high accuracy. Their compact size, good performance, and novel appearance make them ideal for science research, technical colleges, industry, and electronic appliance maintenance.

Permanent Operations

These power supplies provide one adjustable output with maximum currents as follows:

• PeakTech 6015 A: 5 A DC
• PeakTech 6035 D: 2.5 A DC

To extend the operational lifespan, it is recommended to limit continuous operation at full load to eight hours daily.

Controls and Description - PeakTech 6035 D

The PeakTech 6035 D features digital displays and controls:

• 1. Amp and Volt Display: Indicates output current and voltage using a 3-digit LCD.
• 5. Voltage Regulator: For coarse adjustment of the output voltage.
• 7. Power Switch: Turns the unit ON when depressed.
• 8. Output Terminal (+): Connects to the positive terminal of the load.
• 9. Case Ground: Ground connection.
• 10. Output Terminal (-): Connects to the negative terminal of the load.
• 11. Current Regulator: Adjusts the current limit protection point.
• 12. Constant-Current Indicator: LED illuminates when the unit is in current-regulated state.
• 13. Constant-Voltage Indicator: LED illuminates when the unit is in voltage-regulated state.
• 15. Output Terminals: Fixed 12 V / 0.5 A output.
• 16. Output Terminals: Fixed 5 V / 0.5 A output.

Operating Method

1. Constant Voltage (CV) Output: Rotate the Current Regulator (11) clockwise to maximum. Turn on the Power Switch (7). Adjust the Voltage Regulators (4 and 5) until the desired output voltage is reached. The Constant-Current indicator (12 or 14) will turn off, and the Constant-Voltage indicator (6 or 13) will light up.
2. Constant Current (CC) Output: Turn on the Power Switch (7). Rotate the Voltage Regulators (4 and 5) clockwise to maximum. Rotate the Current Regulator (11) counterclockwise to minimum. Connect the load. Adjust the Current Regulator (11) clockwise until the desired output current is reached. The Constant-Voltage indicator (6 or 13) will turn off, and the Constant-Current indicator (12 or 14) will light up.
3. Setting Current Limit: For CV output, the Current Regulator (11) is typically set to maximum. However, the current-limiting protection point can be set arbitrarily. To set the limit: Turn on the unit, rotate the Current Regulator (11) counterclockwise to minimum. Short the positive and negative output terminals. Rotate the Current Regulator (11) clockwise until the output current matches the desired current-limiting protection point. Disconnect the shorted terminals.

Caution

These units feature excellent protection, including adjustable current-limit protection. A control circuit manages transistor power loss, minimizing damage during short circuits. While power loss still occurs, it is not high enough to damage the unit. However, to reduce aging and energy consumption, faults should be identified and power turned off promptly.

After operation, store the unit in a dry, well-ventilated area and keep it clean. If not in use for extended periods, unplug the power supply for storage.

Always disconnect the input voltage before performing any maintenance.
