1200V 20A Industrial DC Power Supply

The 1200V 20A Industrial DC Power Supply is a unidirectional DC power supply rated at 1200 V and 20 A for industrial DC power conversion projects. The published rating defines the available DC envelope; it does not replace process calculations or establish the normal operating setpoint.

Published Rating and Electrical Boundary

Rated DC output	1200 V DC, 20 A DC
Application	industrial DC power conversion
Regulation	Constant-current or constant-voltage main mode, selected for the confirmed process
AC input	AC 380 V or 415 V. Final phase, frequency and site conditions must be confirmed.

This product follows Gao Hui’s low-voltage AC input, high-frequency switching and isolation, one-way DC architecture. It is not presented as an external DC-input converter, AC-output source, bidirectional or regenerative supply, or medium/high-voltage direct-input system.

Application and Selection

This page applies to a defined AC-input, one-way DC-output industrial load Select from the actual load curve, continuous/peak current, voltage range, duty and transient behavior. Include connection losses and the maximum load voltage under real operating conditions.

The load and process must be identified before the power supply can be treated as suitable.

Working-point focus: the nameplate rating is an available ceiling, not a recommended operating recipe. The normal working current and voltage must come from the validated process window and actual load.

Information Required for Selection

• load type
• working and maximum voltage
• continuous and peak current
• duty cycle
• load dynamics
• connection losses
• control sequence
• site and cooling conditions

Also provide the site AC voltage, phase and frequency; cable distance; daily duty; ambient conditions; cabinet location; required local or remote control; and any interface or interlock list. Gao Hui engineering can then check the practical working range against the published rating.

Configuration Boundary

The confirmed standard scope is limited to the published DC rating and stated process use. Cooling method, enclosure, control interface, ramp, timer, ampere-hour control, pulse waveform, polarity reversal, communications, ripple target and redundancy are project-specific. They are supplied only when written into the confirmed configuration and must not be inferred from a legacy title, image or category.

Frequently Asked Questions

Is the rated current the normal process current?

No. The rating is the product ceiling; the working setpoint must follow the validated process window and actual load.

Can the process name determine the final voltage?

No. Loaded voltage depends on chemistry or load behavior, spacing, contacts, conductors and the production arrangement.

Are pulse, reversal and communications included?

Only when they are written into the confirmed configuration. They are not assumed from the product title.
