Functions

Maintenance-Free DC UPS

Capacitor energy storage eliminates battery maintenance and supports a 0.15 minute buffer time for short supply interruptions.

Automatic Buffer Operation

The unit monitors the 24 V DC supply and transfers the load to stored energy when the configured response threshold is crossed.

Flexible Buffer Threshold

The preset response value is 22.5 V and can be adjusted from 22 to 25.5 V in 0.5 V steps.

Expandable Storage

The UPS500S basic device can be extended with compatible SITOP UPS501S expansion modules for longer buffering times.

Interfaces

USB PC Interface

The integrated USB interface supports PC connection for configuration, monitoring and service functions.

Status Signaling

LED indicators and floating changeover contacts provide operating, buffering, alarm and capacitor-capacity status.

Input and Output Terminals

Input uses two screw terminals and output uses four screw terminals for 1 to 4 mm2 conductors.

Control and Status Terminals

Ten screw terminals accept 0.5 to 2.5 mm2 conductors for control and signaling circuits.

Installation

DIN-Rail Mounting

Snap the 120 mm wide unit onto an EN 60715 35 x 7.5/15 DIN rail inside a suitable control cabinet.

Required Clearances

Maintain 50 mm free space above and below the 125 mm high enclosure; no side clearance is required.

Power Wiring

Verify a 24 V DC source within the 22 to 29 V input range before connecting the 15 A output load.

Commissioning Checks

Confirm polarity, USB configuration, 1 A or 2 A charging-current setting and the selected buffer response threshold.

Protection & Environment

Electrical Protection

The output is short-circuit proof. Reverse-polarity protection is provided for the input and energy-storage connection.

Environmental Limits

Operate from 0 to 60 degrees C with natural convection; transport and store from -40 to +70 degrees C.

Enclosure and EMC

IP20, protection class III, EN 55022 Class B for emitted interference and EN 61000-6-2 for immunity.

Approvals

CE marked, UL/cULus listed, EAC approved, and suitable for shipbuilding applications with ABS and DNV approvals.

FAQ

Q1. How can I verify that the quoted unit is the exact model?

Require a current nameplate photo showing 6EP1933-2EC51 and SITOP UPS500S. Compare the 24 V DC / 15 A rating, 5 kWs capacitor storage, USB interface and 120 x 125 x 125 mm enclosure with the Siemens data sheet.

Q2. How can I distinguish new, used and refurbished stock?

Request dated photos of the complete unit, factory label, terminals, DIN-rail clip and packaging. Check for mounting marks, terminal scratches, dust, replaced labels or signs that the enclosure has been opened.

Q3. How can I verify that the supplier is legitimate and reliable?

Check legal registration, traceable business address, matching bank details and a written quotation that states the complete order number 6EP1933-2EC51 without shortening or changing the suffix.

Q4. What should an engineer confirm before purchase?

Confirm 24 V DC input, the 22 to 29 V range, 15 A output, 5 kWs storage, 0.15 minute buffer time, USB interface, IP20 rating, DIN-rail mounting and the available 120 x 225 mm installation space.

Q5. What physical evidence should be requested before payment?

Ask for dated photos or video showing the full 6EP1933-2EC51 nameplate, serial information, all screw terminals, USB port, housing condition, packaging and quantity, with the complete model readable.

Q6. Can a similar SITOP UPS500S model or suffix replace it?

Not automatically. A substitute must match the 24 V DC / 15 A output, 5 kWs capacitor capacity, buffer behavior, USB interface, dimensions, mounting and approvals. Obtain engineering approval before substitution.
