1. MAIDA DEVELOPMENT COMPANY Recommended Products for the Lighting Industry (757)

2. INTRODUCTION
The Lighting Industry is diverse. The surge protection requirements vary depending on the application and the desired market, i.e. residential vs. commercial. Also, the safety agency (UL, ANSI, CSA, etc) testing requirements differ depending on the installation.
Typical protection applications include:
Photo Controls
LED Drivers
LED Arrays
Fluorescent Ballasts
Halogen Fixtures
Traffic Lights
For the protection of the products listed, Maida typically provides the following product lines:
Standard Series
HC Series
MLV Series
MPD Series

3. Common Testing Required for Lighting Products

The required coupling modes, polarity and phase angle, and DUT configuration is dependent on the type of DUT. The following requirements are for control devices.
Coupling Modes*
L1 to L2
Polarity and Phase Angle
Positive at 90° and Negative at 270°
DUT operational state
Controlled device ON, Controlled device OFF
Standard Life:  Total Number of Strikes for devices
5 strikes x 1 coupling modes x 1 polarity/phase angle (Positive at 90°, controlled device maximum specified input voltage.
With a second DUT, 5 strikes x 1 coupling modes x 1 polarity/phase angle (Negative at 270°, controlled device maximum specified input voltage.
10 total strikes, split between 2 DUTs.

4. Maida Products – Recommended Lighting Applications
STANDARD SERIES VARISTORS
UL1449, cUL, CSA, VDE approvals, RoHS/REACH Compliant, the Standard Series is our broadest and most comprehensive line of radial-leaded varistors. Available in sizes from 5mm to 25mm, and MCOV from 11VAC to 1000VAC (additional voltages available upon request). Designed to handle low and medium voltage.
The Standard Series is recommended for use in the ANSI “Typical “, and possibly “Enhanced” test level/configuration. Can be used in the “Extreme” with proper parallel MOV configuration. Also, very commonly used in fluorescent ballast’s. Also used for supplementary protection in LED Drivers.
HC SERIES VARISTORS
UL1449, cUL approvals, RoHS/REACH Compliant, the HC Series is designed for pulse repetition and/or higher surge current environments. Typical uses are LED lighting, photo controls, GFCI / AFCI / LCDI applications. Available in sizes from 8mm to 25mm, and MCOV from 130VAC to 550VAC.
The HC Series is recommended for use in all ANSI test level / configurations. The HC Series has widespread use in the Photo Control industry, primary LED Driver protection, and SPD modules for total lighting protection.
MLV SERIES VARISTORS
RoHS/REACH Compliant, the MLV Series is a surface mount, multilayer MOV. Designed to provide transient, and ESD protection in EIA 0402, 0603, 0805, 1210, 1812, 2220 chip sizes, and MCOV from 4VAC to 300VAC (additional voltages available upon request).
The MLV Series is commonly used for LED Array protection. These are typically installed on the LED array itself.
MPD SERIES
UL1449 Type 4CA, cUL, a modular surge protective device, featuring an IP65 enclosure, utilizing thermal protection with MOV’s to provide a complete protection package. Can be connected in series or parallel with the load, operational indictor, and MCOV of 120VAC, 277VAC, 347VAC and 480VAC. Nominal Discharge Current (IN) rating of 5kA or 10kA and an IMAX of 10kA or 20kA. Used heavily in the lighting industry for LED street lighting, roadway lighting, parking/garage lighting, and digital signs.
The MPD Series is recommended for total lighting protection. This product is designed to protect all modes, while safely disconnecting itself from the circuit in case of sustained overvoltage conditions, or surge conditions exceeding recommended levels.
Can be used in series or parallel with the load allowing the customer versatility.
