SNP-9034 Skynet Electronics 5V±15V Power Supply Connectors Module
Product Overview
The Skynet SNP-9034 is a 30-watt open frame switching power supply delivering three regulated DC output rails simultaneously: +5V at 1.5A, +15V at 1.2A, and -15V at 0.3A. With universal AC input range (90VAC to 260VAC) and worldwide frequency tolerance (47Hz to 63Hz), this power supply operates seamlessly across global mains supplies.
Designed for PLC systems, industrial machine control boards, measurement equipment, and embedded electronics, this compact supply provides both logic-level (+5V) and analogue-rail (±15V) power in a single unit measuring just 70 × 130 × 32.1 mm.

Triple Output Architecture
The SNP-9034 combines +5V for digital logic, microcontrollers, and PLC I/O circuitry with ±15V for operational amplifiers, analogue signal conditioning, and precision instrumentation. This classic power architecture eliminates the need for multiple power supplies or DC-DC converters in mixed digital/analogue systems.
Universal Input Compatibility
With automatic voltage adaptation from 90VAC to 260VAC, this supply operates worldwide without modification. The 47-63Hz frequency tolerance covers both 50Hz and 60Hz mains systems, while >16ms hold-up time ensures stable operation through brief power interruptions.
Open Frame Design
The open frame construction allows for easy integration into equipment chassis. Standard M3 mounting holes (60 × 120 mm pattern) and industry-standard Molex terminal block connectors ensure straightforward installation and maintenance.
Certifications & Compliance
UL, CSA, and VDE safety certifications, plus FCC Class B and VDE Vfg 243/1991 EMI compliance, make this supply suitable for equipment destined for North American, Canadian, and European markets.
Frequently Asked Questions
Can the SNP-9034 be used on both 115VAC and 230VAC mains supplies?
Yes. The universal input range (90VAC to 260VAC) allows operation on any standard mains voltage worldwide without hardware changes or configuration.
What is crowbar over-voltage protection?
Crowbar protection short-circuits the affected output when voltage exceeds safe thresholds, protecting downstream circuitry. This safety feature activates during internal faults and requires a power cycle to reset.
Can output rails be loaded independently?
Each rail can operate from 0A load with no mandatory minimum requirements. Peak current ratings provide headroom for startup inrush and transient load spikes.
Are the connectors easy to source for replacement?
Yes. Both AC input (Molex 5277-2) and DC output (Molex 5273-x) connectors use industry-standard terminal blocks with wide availability and compatible equivalents.
Is this suitable for PLC control panels?
Yes. When installed in a properly grounded enclosure with restricted access to live parts, the SNP-9034 meets requirements for industrial control panels and equipment chassis.
