Description

The High Perfection Technology LP1020-12-C0700 is a single output constant current LED driver / power supply. It has a 700mA constant current and a voltage output of 7 - 12Vdc. The LP1020-12-C0700 has a maximum output of 20 watts. It can operate on an AC input voltage from 110 - 277V. The LP1020-12-C0700 is not dimmable. It is cULus and CE approved. It has a compact footprint of 3.74 x 1.57 x 0.98 inches.

A constant current LED driver is a type of power supply specifically designed to regulate the current flowing through one or more LEDs. Unlike constant voltage drivers, which maintain a steady voltage, constant current drivers ensure a consistent current supply, regardless of fluctuations in voltage or the number of LEDs connected.

Here's a breakdown of how they work and why they are important:
How Constant Current LED Drivers Work:
1. Current Sensing: The driver continuously monitors the current flowing through the LED circuit using a sensing element like a resistor or transformer.
2. Comparison: It compares the sensed current to a pre-set reference value.
3. Voltage Adjustment: If the sensed current deviates from the reference, the driver adjusts the output voltage to bring the current back to the desired level.
4. Constant Output: This feedback loop ensures that the LEDs receive a stable and consistent current, preventing them from drawing too much or too little current.

Why are Constant Current LED Drivers Important?
- LED Sensitivity: LEDs are highly sensitive to changes in current. Even small variations can cause significant changes in brightness, color, and lifespan.
- Preventing Damage: Supplying too much current can lead to overheating and premature failure of the LEDs. Constant current drivers protect the LEDs by ensuring they operate within their specified current range.
- Consistent Brightness: By maintaining a stable current, constant current drivers ensure consistent brightness across all connected LEDs, even if the voltage requirements vary slightly.
- Thermal Runaway Prevention: LEDs can experience thermal runaway, where increased temperature leads to increased current, further increasing the temperature. Constant current drivers help prevent this by regulating the current and keeping the LEDs within their safe operating temperature.

Types of Constant Current LED Drivers:
- AC Input: These drivers convert AC voltage from the mains power supply to a constant DC current output.
- DC Input: These drivers operate on DC voltage, often used in applications powered by batteries or solar panels.
- Dimmable: These drivers allow for adjusting the brightness of the LEDs using dimming control signals like 0-10V, DALI, or PWM.
- Non-dimmable: These drivers provide a fixed current output and do not support dimming.

Applications of Constant Current LED Drivers:
Constant current LED drivers are commonly used in various LED lighting applications, including:
- Downlights
- Wall packs
- Area lights
- Sconces
- Stage lighting
- Commercial office lighting
- Hospitality lighting
In summary, constant current LED drivers are essential components for ensuring the proper operation, longevity, and consistent performance of LED lighting systems. They protect the LEDs from damage by regulating the current supply and maintaining stable brightness.

Semperlite.com Returns Policy

How to set up a Return

1. Sign In to your Account ( https://www.semperlite.com/secure/login )
2. Click on "Order History", and search for the appropriate order using either the Date, Customer PO, Item Name or Order ID.
3. Next to the order you wish to return an item from click the "Order Details" button.
4. If the order was shipped in the last 30 days, you can click "Return this Item".
5. Next you must fill out the questionnaire about your return and once you submit that you will see an estimated refund amount for the return. Return.
6. Next you will receive an RMA Approval email, it will include your RMA #, make sure to write that number on the outside of box.
7. Last, within 24 hours of your RMA Approval you will receive a return label via email. If that return label is used to return your order, the label price will be deucted from your refund/credit.

Requirements / Restrictions

All returns must be started within 30 days of the order's ship date.
All returns must include an authorized RMA number on the outside of the package.
All returns must be shipped back in a box, envelopes or bubble mailers are not acceptable.
Any item listed as discontinued or being phased out is non-returnable.
All items marked as "Special Order item" are non-cancelable and non-returnable.
Any item that was sold at a discounted price is non-returnable.
The costs of returning non-defective products to us are the responsibility of the customer.
In order to receive a store credit or refund, products must be returned in working order and in their original, undamaged packaging.
All orders shipped outside of the USA/Canada are non-returnable.
We will not be responsible for covering defective products for orders shipped outside of the USA.
We do not offer expressed or implied a warranty on any items. Any issue with a warranty claim must be handled directly with the manufacturer.

Restock Fee

If a product is returned and is in full operating order, a restocking fee of 10% will automatically be deducted from any refundable amount.
If an order is returned without authorization or an RMA #, a 40% restocking fee will be deducted from any refundable amount.

Why is there a Restock Fee?

When we process a return for non-defective product, we have significant labor costs to process the inbound shipment and to test that product is valid for resale. And if/when we return special order products to the manufacturer, we are assessed a 25% minimum restock fee ourselves.
Our restock fee is less than HALF of the typical fee the our competition charges.

Damage / Missing Shipment or Items

Customer is responsible to open and inspect your shipment within 48 hours of receipt.
All shipment issues for damage, shortage or wrong items must be reported within 48 hours of delivery.
Any missing shipments must be reported within 14 days of the order ship date for full reimbursement.
