We specialize in manufacturing heating stages and various non-standard customized electric heaters with robust, durable construction and reliable quality. Shenzhen Bangqi Chuangyuan Technology has earned consistent praise from global customers. Welcome to contact us for heating platform inquiries! This electric hot plate adopts original Yudian AI PID digital temperature controller with high precision, safe, straightforward and user-friendly operation.

1. Original genuine Yudian AI PID digital temperature controller, high precision, safe and intuitive operation.
2. High-performance solid-state SSR relay with service life 100 times longer than ordinary mechanical contact relays.
3. Multiple premium stainless steel heating tubes for quick easy maintenance and ultra-low failure rate.
4. Solid pure aluminum heating panel with outstanding thermal conductivity for fast, uniform heat distribution.
5. Full machine housing fabricated from imported SUS304 stainless steel; no paint peeling or rusting under standard working environments.

Power Supply: AC220V 50Hz
Temperature Control Range: Ambient ~ 350℃
Temperature Control Accuracy: ±1%℃
Two Types: Integrated Model (Overall Height 150mm), Split Model (Heating Plate Thickness 65mm)

Custom non-standard sizes and dimensions are available upon request.

1. Constant temperature heating for glue dispensing and encapsulation in all electronics manufacturing sectors.
2. LED aluminum substrate chip soldering and rework repair.
3. Mold core preheating for mold factories.
4. Sample baking, drying and thermal testing across all industrial fields; essential laboratory instrument for biology, genetics, medical hygiene, environmental protection, biochemistry, analytical testing and educational research labs.

1. Connect power supply and turn on the main power switch. The green power indicator light stays lit to confirm power input.
2. Toggle heating switch to activate the unit. Solid red heating lamp = continuous temperature rise; flashing red lamp = constant temperature mode with intermittent heating cycles.
3. After finishing work, turn off heating switch first to stop heat output. The green power lamp remains illuminated as a safety warning — do not touch the hot surface. Wait at least 1 hour for the working plate to fully cool down before cutting main power supply.

1. Rated operating voltage AC220V; must use grounded three-hole socket equipped with residual current protection switch.
2. Untrained personnel shall not open machine casing or modify internal wiring arbitrarily.
3. Do not touch heating surface directly by hand to avoid scald injuries.
4. Cut off power completely when leaving unattended or storing long-term.
5. This unit is equipped with air cooling system; never block side air intake vents.
6. Unplug power cord fully before replacing fuse tube to prevent electric shock hazards.

• PV: Measured value / mode display value <: Digit shift key
• SV: Setpoint value / mode parameter display value ∨: Value decrease key
• OP1: Output indicator lamp ∧: Value increase key
• AU1: Alarm 1 indicator ○: Set mode / confirm key
• AU2: Alarm 2 indicator lamp

7.1 Enter Parameter Menu

Long press the ○ key on the left to access the parameter list shown below.

7.2 Set Target Temperature Value

Under standard display interface, adjust the SV setpoint value via ∧, ∨ and < keys. ∨ decreases value, ∧ increases value; the blinking decimal point marks the editable digit (cursor). Press and hold the key for rapid increment/decrement with two-speed acceleration as the cursor shifts right. The < key moves the blinking cursor directly for fast digit editing; adjust the highlighted digit with ∧ / ∨.

7.3 Auto-Tuning (AT) Operation for PID Parameters

When running AI intelligent PID control, execute Auto-Tuning (AT) to calculate optimized PID coefficients. Under main display page, hold the < key for 2 seconds to enter AT parameter. Use ∧ to switch the lower display window from OFF to ON, then press ○ confirm key to start auto-tuning. The lower screen will flash “At” during calculation. After two temperature oscillation cycles, the internal microprocessor automatically calculates matching PID parameters and exits tuning mode.

To abort tuning early: hold < for 2s to recall AT menu, set ON back to OFF and confirm with ○ key.

Notes: PID values calibrated under different setpoints differ significantly. Always set SV to your most commonly used working temperature before starting auto-tuning; do not change SV during tuning process. Control performance may not reach optimum immediately after AT completion; the built-in self-learning algorithm will refine stability after several hours of continuous operation.

1. 1-year free full-unit warranty under normal usage excluding man-made damage; heating tubes carry a 6-month separate warranty.
2. Paid lifetime maintenance service available after warranty expiration.

Important Reminders

1. If the unit shows no power response upon first startup, shipping vibration may loosen internal power terminals. Open the bottom cover and inspect wiring connections.
2. Initial heating may overshoot the set temperature by 3–5℃ and stabilize after several minutes. This design improves overall surface temperature uniformity.
3. All units complete a 24-hour continuous aging test before factory shipment. Unauthorized modification of internal parameters voids warranty; our company shall not bear liability for equipment failure or personal injury caused by improper manual parameter editing.
