Product Overview

The APC-12 series is MEAN WELL's 12.6W constant-current LED driver with OVP protection -- a significant upgrade over the APC-8 in a larger 77x40x29mm platform. Unlike the APC-8 which relies solely on short-circuit protection, the APC-12 adds over-voltage protection with diode clamping, making it suitable for LED installations where fault tolerance is critical.

The APC-12 accepts 90~264Vac with 0.2A/230V, 0.35A/115V and 70A inrush. Two fixed current options with +/-8% accuracy: 350mA (9~36V/12.6W) and 700mA (9~18V/12.6W). The 350mA variant covers a very wide 9~36V compliance range, supporting everything from 3-LED strips to 12-LED series arrays. Efficiency: 80% (700mA) and 82% (350mA). No-load output voltage is 48V (350mA) / 24V (700mA).

The APC-12 features full protection suite: OVP with diode clamping (39.6~46.8V for 350mA, 20.7~24.3V for 700mA) plus short-circuit protection. This is a key differentiator from the APC-8's SC-only design. The Class II plastic shell with IP42, Class 2 / LPS certifications, and fly leads (Brown/Blue input 20AWG, Red/Black output 18AWG, 150mm) are standard MEAN WELL LED driver features. Operating temperature is -30~+70C (wider than APC-8's -15C minimum).

Certifications: UL8750, CSA C22.2 No.250.0-08, BIS IS15885 (all models), EAC, BS EN/EN62368-1. 3.75KVac I/P-O/P. 0.08kg, 120 pcs/carton (11.8kg). 2-year warranty. ⚠ Not for EU/CN LED lighting. 100% full-load burn-in tested. At 230V, can configure 17 units on a B-curve / 29 units on a C-curve 16A breaker.

Key Features

OVP Protected CC Driver -- Upgrade from APC-8
The key advantage over APC-8: over-voltage protection with diode clamping. If LEDs fail open-circuit, OVP activates at 39.6~46.8V (350mA) / 20.7~24.3V (700mA) -- protecting downstream components. SC protection also standard.

12.6W Rated Power -- 50% More than APC-8
Both 350mA and 700mA models deliver the full 12.6W. The 350mA variant's 9~36V compliance range is the widest in the APC family -- drive 3 to 12 series LEDs from a single driver.

Class 2 + LPS -- US Market Ready
Class 2 (<2A, <100W) and LPS (Limited Power Source) certifications reduce installation complexity -- no conduit required, no electrician certification in many jurisdictions for <60V DC LED circuits.

29 Units on One 16A C-Curve Breaker
Low 0.2A/230V AC current means 29 APC-12 drivers on a single 16A C-curve breaker -- ideal for large signage installations with dozens of independent LED strings.

-30~+70C Wide Temperature Range
Twice the cold-range capability of APC-8 (-30C vs -15C). Suitable for outdoor signage in unheated enclosures, cold storage LED lighting, and year-round outdoor applications.

UL8750 + BIS All Models -- Global Certified
LED-specific safety UL8750 for North America, CSA for Canada, BIS IS15885 for India (both models), EAC for Russia/Eurasia, BS EN/EN62368-1 for general safety. 2-year warranty with 100% burn-in.

Frequently Asked Questions

How is APC-12 different from APC-8?

APC-12 is a 1.5x power upgrade with OVP protection in a larger 77x40mm chassis. Key differences: 12.6W vs 8W, OVP protection added (diode clamping -- absent on APC-8), wider temperature range (-30C vs -15C minimum), Class 2/LPS certified (not on APC-8), only 2 current options (vs 4 on APC-8), larger size (77x40x29mm vs 60x30x23.5mm). APC-8 has higher MTBF (14,511K vs 6,418K) due to simpler topology. Choose APC-12 when you need OVP protection and/or 50% more power; choose APC-8 when reliability and compact size are priorities.

How do I choose between 350mA and 700mA?

The 350mA variant has a 9~36V compliance range -- the widest in the APC family, supporting 3-12 series LEDs. It delivers 12.6W at 36V. The 700mA variant has a 9~18V compliance range, supporting 3-6 series LEDs, also at 12.6W. Rule of thumb: for long LED strings (many LEDs in series), use 350mA. For high-brightness short strings (few LEDs in series), use 700mA. Match your LED's rated forward current to the driver current.

What happens when LEDs fail open-circuit on APC-12?

Unlike APC-8 which has no OVP and lets output float to no-load voltage, the APC-12 activates OVP diode clamping: 39.6~46.8V for the 350mA model, 20.7~24.3V for the 700mA model. The output shuts down, protecting connected LEDs and downstream components. This is the primary reason to choose APC-12 over APC-8 -- fault tolerance in critical LED installations.

What does Class 2 and LPS mean for installation?

Class 2 (NEC/UL) limits output to <100W and <60V DC, meaning the APC-12's output circuits don't require conduit or special wiring methods in the US. LPS (Limited Power Source, IEC/EN62368-1) is the international equivalent. Together they simplify installation: fewer NEC requirements, no need for a licensed electrician to wire the output side. This is not available on APC-8.
