CCC PSMU-350-34 Industrial Power Supply Module – 34 V, 350 W for Control Cabinets

The CCC PSMU-350-34 is a 350 W industrial-grade power supply module built for stable 34 VDC output in factory automation, motion systems, and test rigs where uptime is everything. From my experience, this 34 V range is a sweet spot for servo amplifiers, mid-voltage DC actuators, and custom machine assemblies that don’t want the heat or losses of step-up stages. You might notice that it blends the usual industrial safeguards—overvoltage, short-circuit, and thermal protection—with the sort of wiring convenience panel builders actually want.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express delivery: FedEx, UPS, DHL

Key Features

• 34 VDC single output (350 W class) – Suited to mid-voltage motion drives, valves, and instrumentation that prefer a clean 34 V rail.
• Universal AC input – Typically supports 85–264 VAC, 47–63 Hz, making it practical for multi-site deployments.
• Industrial protections – OVP/OCP/SCP/thermal safeguards help protect loads and reduce unplanned downtime.
• Stable regulation – Designed for low ripple and good transient response under varying machine loads.
• Cabinet-friendly form factor – Panel/chassis mounting fits standard control panels; DIN-rail mounting possible with bracket in many cases.
• Status signaling – Many units in this class provide DC-OK or remote enable; this model appears to support similar control signals.

Application Fields

This model is commonly used where a clean 34 V rail is preferred over 24 V for headroom and reduced current. Typical deployments include:

• Motion control and servo stages that run best near 34 VDC
• Automated assembly, labeling, and packaging lines with mixed-voltage I/O
• Industrial PCs, machine vision lighting bars, and high-power sensors
• Test benches and burn-in racks needing a stable mid-voltage supply
• Custom robotics and AGV subsystems where 24 V isn’t quite enough

Advantages & Value

• Reliability under load – Consistent performance with protections that reduce field failures.
• Compatibility – Universal input and common terminal layouts make retrofits straightforward.
• Cost control – A direct 34 V rail can cut conversion losses and simplify wiring versus DC-DC stages.
• Serviceability – Clear status signaling and accessible terminals help maintenance teams move faster.

Feedback from a packaging OEM: “Swapping to a 34 V bus with this PSU let us downsize our wiring and the drives ran cooler. The team appreciated the predictable behavior when the line surged.”

Installation & Maintenance

• Cabinet standards – Mount in a clean, dry enclosure (IP54 or better for dusty sites). Keep 50 mm clearance around vents.
• Ventilation – Provide continuous airflow; for 350 W loads, forced-air is typically recommended to avoid thermal derating.
• Wiring – Use appropriately rated copper conductors; torque terminals to spec; separate AC input and DC output harnesses to reduce noise.
• Grounding – Bond protective earth; verify cabinet grounding continuity to minimize EMI.
• Safety – De-energize before servicing; bleed time for bulk caps can be >30 s after power-down.

• Routine maintenance – Quarterly dust cleaning; annual check of output voltage and ripple; firmware not typically applicable on passive PSU models.
• Spare strategy – Keep at least one unit on hand for each unique voltage per line to shorten MTTR.

Quality & Certifications

• CE and RoHS compliance expected for this class; UL/cUL listings commonly available on production units
• Manufactured under ISO 9001 quality systems (typical for this series)
• Warranty support: 365 days (replacement or repair as applicable)

Related Accessories & Supporting Components

• DIN-rail mounting bracket for panel conversion
• EMI/RFI AC input filters (to meet stricter site EMC)
• DC distribution terminal blocks and circuit protection (MCB/fuse)
• Buffer/UPS modules for ride-through during short outages

If you’re matching this supply to a servo or lighting load, share peak and steady-state currents—sizing with a small margin typically yields longer life and fewer nuisance trips.
