Electrical specifications

Model and output configuration	SPA01W8-24; isolated, regulated single-output DC/DC converter in a SIP6 package with industry-standard pinout.
Output voltage	24 V DC.
Output current range	0–42 mA. No minimum load is required.
Output power and current limit	1 W total converter rating, subject to the stated current limits and thermal derating. Rounded current figures do not increase this rating.
Input operating range	9–75 V DC, 8:1 input-range family; the selection table lists nominal 12, 24, 36, 48 and 72 V systems.
Input current	7 mA at no load; 55 mA at full load under the general measurement conditions.
Typical efficiency	76% under the general measurement conditions.
Series efficiency capability	The family offers efficiency up to 80% across its models. Use the selected model’s typical value above.
Maximum capacitive load	47 µF.
Input surge limit	100 V DC for 100 ms maximum.
Input filter and recommended fuse	Capacitor network; a 400 mA slow-blow input fuse is recommended.
Output voltage accuracy	±2%.
Ripple and noise	1% of output voltage, peak-to-peak maximum. Measured at 20 MHz using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation	±0.5%, measured from low line to high line at rated load.
Load regulation	±0.5%, measured from 0% to 100% rated load.
Switching frequency	330 kHz typical.
General measurement conditions	Unless otherwise specified: normal 24 V DC input, rated load, 25°C and 70% RH ambient.

Protection, control and thermal operation

Short-circuit protection	Continuous short-circuit protection with automatic recovery.
Overload protection	110–350% of rated output power; automatic recovery after the fault is removed.
Typical under-voltage lockout	Start-up: 8.8 V DC; shutdown: 8 V DC.
Operating and case temperature	−40 to +95°C ambient, subject to derating; case temperature +110°C maximum.
Cooling and load derating	Natural convection: 100% load from −40 to +90°C, falling to 50% at +95°C. Do not extend the specified operating ceiling beyond +95°C.
Working humidity	5–95% RH, non-condensing.
Storage conditions	−55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient	0.05%/°C over 0 to +95°C.
Soldering conditions	At 1.5 mm from the case: 3–5 seconds at 265°C maximum.
Vibration	10–500 Hz, 2 G; 10 minutes per cycle, for 60 minutes along each of the X, Y and Z axes.

Isolation, EMC and reliability

Applicable safety approvals	EAC TP TC 020/2011 approved.
Isolation withstand voltage	Input to output: 1.5 kV DC.
Isolation resistance	Input to output: 1000 MΩ at 500 V DC, 25°C and 70% RH.
Typical isolation capacitance	60 pF.
EMC emission	BS EN/EN 55032 (CISPR 32): conducted N/A; radiated Class A without additional components. The radiated Class B suggestion circuit uses the external components listed below.
ESD immunity	BS EN/EN 61000-4-2: Level 3, ±8 kV air.
Radiated RF immunity	BS EN/EN 61000-4-3: Level 2, 3 V/m.
EFT and surge immunity	BS EN/EN 61000-4-4: Level 1, 0.5 kV; BS EN/EN 61000-4-5: Level 2, 0.5 kV line to line.
Conducted RF and magnetic-field immunity	BS EN/EN 61000-4-6: Level 2, 3 V e.m.f.; BS EN/EN 61000-4-8: Level 1, 1 A/m.
MTBF	Greater than 500 Khrs, MIL-HDBK-217F at 25°C.
Manufacturer warranty	3 years.
EMC suggestion circuit	The BS EN/EN 55032 radiated Class B recommendation uses nominal input and full load. L1 is in series with +Vin; C1 is across the supply before L1 and C2 across the module input after L1. C3 links module-side +Vin to +Vout; C4 links −Vin to −Vout.
Radiated Class B external components	C1 = C2 = 2.2 µF / 100 V; L1 = 10 µH. The catalog labels both C3 and C4 as “152/5 kV”. Confirm the intended capacitor-code specification with MEAN WELL before selecting these parts.

Installation and system verification

Complete-system EMC verification	Verify EMC with the converter installed in the final equipment and connected to a representative load. Wiring, assembly and the application affect the result. Follow the model's specified EMC conditions and any required external components; the linked EMI testing guidance does not certify the finished equipment.
