Model selection and application

Parameter	Details
Full model / series	LPC-150-1750 / LPC-150
Model code	LPC-150 identifies the series; the final code 1750 denotes 1750 mA output current. Use the actual power below, not the series number, for load sizing.
Load selection	Use an LED load requiring 1750 mA whose total operating voltage stays within 43-86 V DC. This is a current-regulated output; the voltage range is not an adjustable constant-voltage setting. Keep within the power and derating limits.
Intended use	Suitable for LED-related fixtures or appliances such as decoration or advertising devices. The manufacturer states that this product is not intended for LED lighting luminaire applications in the EU and China. The installation manual additionally limits this series to devices whose primary use differs from lighting (for example copiers or overhead projectors), or scale and display lighting.

Output and dynamic performance

Parameter	Details
Rated output current	1750 mA
Constant-current region / power	43-86 V DC; catalog rated power 150.5 W.
Current accuracy / ripple	Current accuracy ±5.0%; current ripple ±5%.
Voltage tolerance	±2.0%; separate from current accuracy.
Constant-current operating window	The catalog describes constant-current operation within 50-100% of rated output voltage. Use the exact model voltage range above and reconfirm special electrical requirements for the final system.
Setup / rise and hold-up	1000 ms setup / 80 ms rise at 230 VAC, full load. Typical hold-up: 16 ms at 230 VAC, full load.
Measurement basis	230 VAC input, rated load and 25°C ambient unless specified otherwise. Typical values vary with operating conditions.

Input and electrical planning

Parameter	Details
Rated input	180-305 VAC, 47-63 Hz; 254-431 VDC.
AC input current / efficiency	1.7 A at 230 VAC; 1.5 A at 277 VAC; typical efficiency 90% at catalog conditions.
Cold-start inrush, typical	40 A at 230 VAC; 750 µs pulse width measured at 50% of peak.
Leakage current	<0.25 mA at 277 VAC.
Input derating	At 60 Hz the low-line curve starts at 80% load at 180 VAC and rises to the 100% plateau near 200 VAC. Use the original static-characteristic graph for the low-line transition; do not assume full output at 180 VAC. Also apply the thermal limit; input and temperature limits are not independent allowances.
16 A breaker reference	At 230 VAC, the catalog lists 3 units on Type B or 6 units on Type C 16 A circuit breakers. Assess the actual installation and circuit conditions.

Protection behavior

Parameter	Details
Short circuit	Hiccup mode with automatic recovery after fault removal.
Overvoltage	96-115 V; output shutdown and latch-off; re-power to recover.
Overtemperature	Output shutdown, automatic recovery after temperature falls.

Environment and derating

Parameter	Details
Working temperature	-25 to +50°C.
Cooling / load derating	Free-air convection in the horizontal orientation shown. The curve shows full load from -25 to +50°C and ends at +50°C. It does not authorize reduced-load operation beyond +50°C.
Humidity and storage	10-95% RH working, non-condensing. Storage: -40 to +70°C, 10-95% RH.
Temperature coefficient / vibration	±0.03%/°C over 0 to 50°C. Vibration: 10-500 Hz, 2 G; 10 min/cycle and 60 min along each X, Y and Z axis.
IP67 enclosure and exposure	Fully encapsulated plastic enclosure; suitable for indoor use or outdoor use without direct sunlight exposure. Do not immerse or operate the supply in water, as required by the installation manual. The catalog footnote cautions against immersion exceeding 30 minutes; this is not permission to use the product submerged. Provide the required protection for the completed wiring; IP67 is not unconditional outdoor permission.
Altitude derating	For this fanless model above 2000 m (6500 ft), reduce allowable ambient temperature by 3.5°C per additional 1000 m.

Wiring, dimensions and installation

Parameter	Details
Dimensions / mounting	191 x 63 x 37.5 mm (L x W x H); drawing tolerance ±1 mm. Two Ø4.5 mm mounting features; case LPC-150. Use the drawing to position mounting hardware.
Input leads	SJTW, 18 AWG, 330 ±20 mm. Brown = AC/L; blue = AC/N, as shown in this model drawing.
Output leads	SJTW, 18 AWG, 320 ±20 mm. Red = +V; black = -V. Observe load polarity.
Insulation / installation	Class II design with no FG connection. Before installation or maintenance, disconnect from the utility and prevent inadvertent reconnection. Keep ventilation clear and do not stack objects on the supply. Maintain 10-15 cm clearance when an adjacent device is a heat source. Nonstandard orientation or high ambient temperature requires output-current derating. Select approved primary and secondary cables rated at least for the unit current. Provide system-level insulation and isolation around interconnections; cover single-insulated wires with the system enclosure. Do not open the case. Have faults examined by a qualified technician; damaged external cables must be replaced by the manufacturer, its service agent or a similarly qualified person.
DC input wiring	Rated DC input: 254-431 VDC. Before DC connection, verify the manufacturer polarity instructions for this exact model; do not infer the L/N-to-positive/negative mapping from another series.
Case-temperature point	The mechanical drawing marks the T case / tc measurement location. The adjacent location dimensions are not maximum temperature values.
Connection items	This is a lead-wired module. Choose suitable connection and mounting hardware for the final equipment from the wire and mechanical requirements above.
