Electrical operation and selection

Parameter Specification and conditions
Product type AC inrush current limiter for capacitive loads and multiple power supplies on one AC line.
Model and mounting ICL-16L; L version with a linear enclosure and terminal connections.
Input voltage 180–264 VAC
Line frequency 47–63 Hz
Inrush current limiting 23 A
Continuous AC rated current 16 A continuous; observe the temperature and switching-cycle limits.
AC input apparent-power reference 3680 VA (16 A × 230 VAC). This is the catalog AC input rating, not a regulated DC output power.
Internal consumption <1.5 W at 264 VAC, 50 Hz input
Operating principle A limiting resistor and an integrated bypass relay are shown in the line conductor; this is not a simple NTC limiter. The block diagram shows the neutral conductor passing through.
Internal relay limiting time, TON 300 ± 50 ms at power-on
Internal relay release time 500 ± 50 ms
Allowed capacitive load 2500 µF maximum
Limiting cycles: PSU setup <250 ms 1 cycle per 5 minutes
Limiting cycles: PSU setup 250–350 ms 1 cycle per minute
Limiting cycles: PSU setup >350 ms 5 cycles per minute; the catalog additionally specifies >1500 ms per cycle.

Protection and operating environment

Parameter Specification and conditions
Internal protection An internal thermal fuse protects against overload and fire. The catalog does not specify automatic reset of this fuse.
Working ambient temperature −30 to +70°C; the dedicated installation manual also specifies a 70°C maximum for ICL-16R/16L.
Working humidity 20–90% RH, non-condensing
Storage temperature −40 to +85°C
Temperature coefficient ±0.03%/°C over 0–50°C; non-condensing conditions
Operating altitude Up to 5000 m. The catalog fanless-model rule reduces permissible ambient temperature by 3.5°C per 1000 m above 2000 m; combine altitude and applicable load derating.
Overvoltage category Category III according to IEC 62368-1, up to 5000 m
Pollution degree 2
Vibration 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes on each X, Y and Z axis. Mounting compliance: IEC 60068-2-6.
Reference test conditions Unless a parameter states otherwise: 230 VAC input, rated load and 25°C ambient.

Dimensions, terminals and installation

Parameter Specification and conditions
Catalog dimensions 175 × 42 × 24 mm (L × W × H); mechanical drawing tolerance ±1 mm.
Mounting Linear enclosure, case PLM-40; follow the model-specific drawing for the end mounting slots and 4.5 mm callouts.
Input terminals TB1: pin 1: AC/N input; pin 2: AC/L input.
Output terminals TB2: pin 3: AC/N output; pin 4: AC/L output.
Terminal-table discrepancy The application diagram identifies TB1 as input and TB2 as output, matching the enclosure INPUT/OUTPUT markings. The mechanical-page pin table repeats “Input” for pins 3 and 4; verify terminal markings and the manufacturer’s wiring information before connection.
Terminal reference SWITCHLAB MB312-750 or equivalent, as listed in the mechanical drawing; a terminal reference does not establish a separately supplied MEAN WELL accessory.
Input and output conductors 0.5–1.5 mm², as specified beside the linear-version drawing.
Cable fixing bar Four grooves: 1.5, 2.0, 2.5 and 3.0 mm. Select the groove for the actual wire diameter; these groove dimensions are not conductor cross-sectional areas.
AC connection arrangement The application diagram places a circuit breaker upstream of the line input, with the downstream power supplies connected in parallel to the limiter output. Use this model’s terminal assignment; R and L versions and different current ratings do not share every pin assignment.
Downstream supply selection Check the combined continuous current, capacitive load and required start/restart cycle against this limiter’s limits. The diagram does not give a universal number of power supplies; confirm the intended combination with the manufacturer.

Dedicated installation-manual requirements

Parameter Specification and conditions
Power isolation and servicing Disconnect the supply before installation, maintenance or modification and prevent inadvertent reconnection. Faults must be examined by a qualified technician; do not open the case yourself.
Controlled installation environment Use a controlled, dry and well-ventilated pollution degree 2 environment. Keep foreign objects and dripping liquid out; avoid high moisture, water and fire sources. Do not touch the unit during operation or shortly after disconnection.
Circuit separation Do not connect the input and output sides together. Follow the exact model terminal assignments and connected equipment requirements.
Copper conductor selection Use copper conductors and fully secure all strands. The manual lists AWG 18/16/14/12/10 with equipment-current guidance of 7/10/15/25/32 A and cross-sections of 0.8/1.3/2.1/2.5/4 mm². With 4–6 connected wires, apply the stated 80% current factor. This is an ampacity guide, not a terminal acceptance range; verify conductor capacity, actual terminals and the intended current.
Selecting the number of power supplies Check both aggregate AC input current and primary storage capacitance. The manual method uses the smaller current-based or capacitance-based unit count, multiplies it by 0.9 and rounds down. Its 19-unit SDR-120-24 example is not a general maximum; use the connected model data and the current ICL specification.
Three-phase applications Use the manufacturer circuit diagrams and qualified system design. In a grid without neutral, the voltage between each pair of live wires must not exceed 264 VAC. This does not create a higher-voltage three-phase rating.
Ventilation clearance Keep ventilation openings unobstructed and allow 10–15 cm from an adjacent heat source.
Terminal tightening torque 5.7 kgf-cm (5 lb-in) for both input and output terminals.
Terminal wire-range distinction The model mechanical drawing specifies 0.5–1.5 mm². The manual’s general ampacity table does not extend this terminal range. Confirm the supplied terminal and conductor selection with the manufacturer for the intended continuous current.
Installation temperature limit The dedicated manual gives a maximum operating temperature of 70°C for ICL-16R/16L. Use the current model specification and installation clearances.
Secure conductors and contacts Insert every strand of stranded wire into the terminal and secure the screw connection. Do not overload one contact; where equipment has multiple output contacts, follow the manual’s requirement to wire each contact.

Conducted and radiated emissions BS EN/EN 55032, Class B
Harmonic current BS EN/EN 61000-3-2, Class A

Conducted immunity BS EN/EN 61000-4-6: level 3, criterion A.
Magnetic-field immunity BS EN/EN 61000-4-8: level 4, criterion A.
Voltage dips and interruptions BS EN/EN 61000-4-11: >95% dip for 0.5 periods; 30% dip for 25 periods; >95% interruptions for 250 periods.
Equipment integration The catalog treats the unit independently; compliance of the complete equipment with EMC directives must still be reconfirmed.

Mass and reliability references

Parameter Specification and conditions
Per-unit mass reference 0.132 kg (132 g), from the catalog PACKING entry. This is the catalog packing reference per unit, not a measured net mass or the whole-carton mass.
MTBF reference 7217.9 thousand hours minimum, Telcordia SR-332 (Bellcore); 2113.8 thousand hours minimum, MIL-HDBK-217F at 25°C.
Manufacturer warranty statement The manufacturer catalog states a 3-year warranty; applicable terms are set by the manufacturer.
